  19. @c Macro definitions for commands and keys
  20. @c =======================================
  21. @c The behavior of the key/command macros will depend on the flag cmdnames
  22. @c When set, commands names are shown. When clear, they are not shown.
  23. @set cmdnames
  24. @c Below we define the following macros for Org key tables:
  25. @c orgkey{key} A key item
  26. @c orgcmd{key,cmd} Key with command name
  27. @c xorgcmd{key,cmd} Key with command name as @itemx
  28. @c orgcmdnki{key,cmd} Like orgcmd, but do not index the key
  29. @c orgcmdtkc{text,key,cmd} Like orgcmd,special text instead of key
  30. @c orgcmdkkc{key1,key2,cmd} Two keys with one command name, use "or"
  31. @c orgcmdkxkc{key1,key2,cmd} Two keys with one command name, but
  32. @c different functions, so format as @itemx
  33. @c orgcmdkskc{key1,key2,cmd} Same as orgcmdkkc, but use "or short"
  34. @c xorgcmdkskc{key1,key2,cmd} Same as previous, but use @itemx

  649. @section Summary
  650. @cindex summary
  651. Org is a mode for keeping notes, maintaining TODO lists, and doing
  652. project planning with a fast and effective plain-text system.
  653. Org develops organizational tasks around NOTES files that contain
  654. lists or information about projects as plain text. Org is
  655. implemented on top of Outline mode, which makes it possible to keep the
  656. content of large files well structured. Visibility cycling and
  657. structure editing help to work with the tree. Tables are easily created
  658. with a built-in table editor. Org supports TODO items, deadlines,
  659. timestamps, and scheduling. It dynamically compiles entries into an
  660. agenda that utilizes and smoothly integrates much of the Emacs calendar
  661. and diary. Plain text URL-like links connect to websites, emails,
  662. Usenet messages, BBDB entries, and any files related to the projects.
  663. For printing and sharing of notes, an Org file can be exported as a
  664. structured ASCII file, as HTML, or (TODO and agenda items only) as an
  665. iCalendar file. It can also serve as a publishing tool for a set of
  666. linked web pages.
  667. As a project planning environment, Org works by adding metadata to outline
  668. nodes. Based on this data, specific entries can be extracted in queries and
  669. create dynamic @i{agenda views}.
  670. Org mode contains the Org Babel environment which allows you to work with
  671. embedded source code blocks in a file, to facilitate code evaluation,
  672. documentation, and literate programming techniques.
  673. Org's automatic, context-sensitive table editor with spreadsheet
  674. capabilities can be integrated into any major mode by activating the
  675. minor Orgtbl mode. Using a translation step, it can be used to maintain
  676. tables in arbitrary file types, for example in @LaTeX{}. The structure
  677. editing and list creation capabilities can be used outside Org with
  678. the minor Orgstruct mode.
  679. Org keeps simple things simple. When first fired up, it should
  680. feel like a straightforward, easy to use outliner. Complexity is not
  681. imposed, but a large amount of functionality is available when you need
  682. it. Org is a toolbox and can be used in different ways and for different
  683. ends, for example:
  684. @example
  685. @r{@bullet{} an outline extension with visibility cycling and structure editing}
  686. @r{@bullet{} an ASCII system and table editor for taking structured notes}
  687. @r{@bullet{} a TODO list editor}
  688. @r{@bullet{} a full agenda and planner with deadlines and work scheduling}
  689. @pindex GTD, Getting Things Done
  690. @r{@bullet{} an environment in which to implement David Allen's GTD system}
  691. @r{@bullet{} a simple hypertext system, with HTML and @LaTeX{} export}
  692. @r{@bullet{} a publishing tool to create a set of interlinked webpages}
  693. @r{@bullet{} an environment for literate programming}
  694. @end example
  695. @cindex FAQ
  696. There is a website for Org which provides links to the newest
  697. version of Org, as well as additional information, frequently asked
  698. questions (FAQ), links to tutorials, etc@. This page is located at

  712. @uref{http://orgmode.org/elpa.html, Org ELPA page}. To see what version of Org
  713. (if any) is part of your Emacs distribution, type @kbd{M-x org-version} (if
  714. your Emacs distribution does not come with Org, this function will not be
  715. defined).}
  716. Installation of Org mode uses a build system, which is described in more
  717. detail on @uref{http://orgmode.org/worg/dev/org-build-system.html, Worg}.
  718. If you have downloaded Org from the Web as a distribution @file{.zip} or
  719. @file{.tar.gz} archive, take the following steps to install it:
  720. @itemize @bullet
  721. @item Unpack the distribution archive.
  722. @item Change into (@code{cd}) the Org directory.
  723. @item Run @code{make help config}
  724. and then check and edit the file @file{local.mk} if the default configuration
  725. does not match your system. Set the name of the Emacs binary (likely either
  726. @file{emacs} or @file{xemacs}), and the paths to the directories where local
  727. Lisp and Info files will be installed. If the Emacs binary is not in your
  728. path, give the full path to the executable. Avoid spaces in any path names.
  729. @item Run @code{make config}
  730. again to check the configuration.
  731. @item Run @code{make install} or @code{sudo make install}
  732. to build and install Org mode on your system.
  733. @end itemize
  734. If you use a cloned Git repository, then the procedure is slightly different.
  735. The following description assumes that you are using the @code{master} branch
  736. (where the development is done). You could also use the @code{maint} branch
  737. instead, where the release versions are published, just replace @code{master}
  738. with @code{maint} in the description below.
  739. @itemize @bullet
  740. @item Change into (@code{cd}) the Org repository.
  741. @item Run @code{git checkout master}
  742. to switch to the @code{master} branch of the Org repository.
  743. @item Run @code{make help}
  744. and then check and edit the file @file{local.mk}. You must set the name of
  745. the Emacs binary (likely either @file{emacs} or @file{xemacs}), and the paths
  746. to the directories where local Lisp and Info files will be installed. If the
  747. Emacs binary is not in your path, you must give the full path to the
  748. executable. Avoid spaces in any path names.
  749. @item Run @code{make config}
  750. to check the configuration.
  751. @item Optionally run @code{make test}
  752. to build Org mode and then run the full testsuite.
  753. @item Run @code{make update2} or @code{make up2}
  754. to update the Git repository and build and install Org mode. The latter
  755. invocation runs the complete test suite before installation and installs only
  756. if the build passes all tests.
  757. @end itemize
  758. If you don't have access to the system-wide directories and you don't want to
  759. install somewhere into your home directory, you can run Org directly from the
  760. distribution directory or Org repository by compiling Org mode in place:
  761. @itemize @bullet
  762. @item Change into (@code{cd}) the Org repository.
  763. @item Run @code{git checkout master}
  764. to switch to the @code{master} branch of the Org repository.
  765. @item Run @code{make compile}
  766. @end itemize
  767. Last but not least you can also run Org mode directly from an Org repository
  768. without any compilation. Simply replace the last step in the recipe above
  769. with @code{make uncompiled}.
  770. Then add the following line to @file{.emacs}:
  771. @example
  772. (add-to-list 'load-path "~/path/to/orgdir/lisp")
  773. @end example
  774. @noindent
  775. If you plan to use code from the @file{contrib} subdirectory without
  776. compiling them, do a similar step for this directory:
  777. @example
  778. (add-to-list 'load-path "~/path/to/orgdir/contrib/lisp" t)
  779. @end example
  780. If you want to include those files with the build and install, please
  781. customize the variable @code{ORG_ADD_CONTRIB} instead in your @code{local.mk}
  782. file, for more details please see this
  783. @uref{http://orgmode.org/worg/dev/org-build-system.html#sec-4-1-2,
  784. description on Worg}.
  785. Installing Info files is system dependent, because of differences in the
  786. @file{install-info} program. The Info documentation is installed together
  787. with the rest of Org mode. If you don't install Org mode, it is possible to
  788. install the Info documentation seperately (you need to have
  789. install-info@footnote{The output from install-info (if any) is system
  790. dependent. In particular Debian and its derivatives use two different
  791. versions of install-info and you may see the message:
  792. @example
  793. This is not dpkg install-info anymore, but GNU install-info
  794. See the man page for ginstall-info for command line arguments
  795. @end example
  796. @noindent which can be safely ignored.}
  797. on your system).

  799. make install-info

  815. default. If you are using an earlier version of Emacs, add this line to your
  816. @file{.emacs} file:
  817. @lisp
  818. (add-to-list 'auto-mode-alist '("\\.org\\'" . org-mode))
  819. @end lisp
  820. Org mode buffers need font-lock to be turned on - this is the default in
  821. Emacs@footnote{If you don't use font-lock globally, turn it on in Org buffer
  822. with @code{(add-hook 'org-mode-hook 'turn-on-font-lock)}}.
  823. There are compatibility issues between Org mode and some other Elisp
  824. packages, please take the time to check the list (@pxref{Conflicts}).
  825. The four Org commands @command{org-store-link}, @command{org-capture},
  826. @command{org-agenda}, and @command{org-iswitchb} should be accessible through
  827. global keys (i.e.@: anywhere in Emacs, not just in Org buffers). Here are
  828. suggested bindings for these keys, please modify the keys to your own
  829. liking.
  830. @lisp
  831. (global-set-key "\C-cl" 'org-store-link)
  832. (global-set-key "\C-cc" 'org-capture)

  836. @cindex Org mode, turning on
  837. With this setup, all files with extension @samp{.org} will be put
  838. into Org mode. As an alternative, make the first line of a file look
  839. like this:
  840. @example
  841. MY PROJECTS -*- mode: org; -*-
  842. @end example
  843. @vindex org-insert-mode-line-in-empty-file
  844. @noindent which will select Org mode for this buffer no matter what
  845. the file's name is. See also the variable
  846. @code{org-insert-mode-line-in-empty-file}.
  847. Many commands in Org work on the region if the region is @i{active}. To make
  848. use of this, you need to have @code{transient-mark-mode}
  849. (@code{zmacs-regions} in XEmacs) turned on. In Emacs 23 this is the default,
  850. in Emacs 22 you need to do this yourself with
  851. @lisp
  852. (transient-mark-mode 1)
  853. @end lisp
  854. @noindent If you do not like @code{transient-mark-mode}, you can create an
  855. active region by using the mouse to select a region, or pressing
  856. @kbd{C-@key{SPC}} twice before moving the cursor.

  861. @cindex maintainer
  862. @cindex author
  863. If you find problems with Org, or if you have questions, remarks, or ideas
  864. about it, please mail to the Org mailing list @email{emacs-orgmode@@gnu.org}.
  865. If you are not a member of the mailing list, your mail will be passed to the
  866. list after a moderator has approved it@footnote{Please consider subscribing
  867. to the mailing list, in order to minimize the work the mailing list
  868. moderators have to do.}.
  869. For bug reports, please first try to reproduce the bug with the latest
  870. version of Org available---if you are running an outdated version, it is
  871. quite possible that the bug has been fixed already. If the bug persists,
  872. prepare a report and provide as much information as possible, including the
  873. version information of Emacs (@kbd{M-x emacs-version @key{RET}}) and Org
  874. (@kbd{M-x org-version @key{RET}}), as well as the Org related setup in
  875. @file{.emacs}. The easiest way to do this is to use the command
  876. @example
  877. @kbd{M-x org-submit-bug-report}
  878. @end example
  879. @noindent which will put all this information into an Emacs mail buffer so
  880. that you only need to add your description. If you re not sending the Email
  881. from within Emacs, please copy and paste the content into your Email program.
  882. Sometimes you might face a problem due to an error in your Emacs or Org mode
  883. setup. Before reporting a bug, it is very helpful to start Emacs with minimal
  884. customizations and reproduce the problem. Doing so often helps you determine
  885. if the problem is with your customization or with Org mode itself. You can
  886. start a typical minimal session with a command like the example below.
  887. @example
  888. $ emacs -Q -l /path/to/minimal-org.el
  889. @end example
  890. However if you are using Org mode as distributed with Emacs, a minimal setup
  891. is not necessary. In that case it is sufficient to start Emacs as
  892. @code{emacs -Q}. The @code{minimal-org.el} setup file can have contents as
  893. shown below.
  894. @example
  895. ;;; Minimal setup to load latest `org-mode'
  896. ;; activate debugging
  897. (setq debug-on-error t
  898. debug-on-signal nil
  899. debug-on-quit nil)
  900. ;; add latest org-mode to load path
  901. (add-to-list 'load-path (expand-file-name "/path/to/org-mode/lisp"))
  902. (add-to-list 'load-path (expand-file-name "/path/to/org-mode/contrib/lisp" t))
  903. @end example
  904. If an error occurs, a backtrace can be very useful (see below on how to
  905. create one). Often a small example file helps, along with clear information
  906. about:
  907. @enumerate
  908. @item What exactly did you do?
  909. @item What did you expect to happen?
  910. @item What happened instead?
  911. @end enumerate
  912. @noindent Thank you for helping to improve this program.
  913. @subsubheading How to create a useful backtrace
  914. @cindex backtrace of an error
  915. If working with Org produces an error with a message you don't
  916. understand, you may have hit a bug. The best way to report this is by
  917. providing, in addition to what was mentioned above, a @emph{backtrace}.
  918. This is information from the built-in debugger about where and how the
  919. error occurred. Here is how to produce a useful backtrace:
  920. @enumerate
  921. @item
  922. Reload uncompiled versions of all Org mode Lisp files. The backtrace
  923. contains much more information if it is produced with uncompiled code.
  924. To do this, use
  925. @example
  926. C-u M-x org-reload RET
  927. @end example
  928. @noindent
  929. or select @code{Org -> Refresh/Reload -> Reload Org uncompiled} from the
  930. menu.
  931. @item
  932. Go to the @code{Options} menu and select @code{Enter Debugger on Error}
  933. (XEmacs has this option in the @code{Troubleshooting} sub-menu).
  934. @item
  935. Do whatever you have to do to hit the error. Don't forget to
  936. document the steps you take.
  937. @item
  938. When you hit the error, a @file{*Backtrace*} buffer will appear on the
  939. screen. Save this buffer to a file (for example using @kbd{C-x C-w}) and
  940. attach it to your bug report.
  941. @end enumerate
  942. @node Conventions, , Feedback, Introduction
  943. @section Typesetting conventions used in this manual
  944. @subsubheading TODO keywords, tags, properties, etc.
  945. Org mainly uses three types of keywords: TODO keywords, tags and property
  946. names. In this manual we use the following conventions:
  947. @table @code
  948. @item TODO
  949. @itemx WAITING
  950. TODO keywords are written with all capitals, even if they are
  951. user-defined.
  952. @item boss
  953. @itemx ARCHIVE
  954. User-defined tags are written in lowercase; built-in tags with special
  955. meaning are written with all capitals.
  956. @item Release
  957. @itemx PRIORITY
  958. User-defined properties are capitalized; built-in properties with
  959. special meaning are written with all capitals.
  960. @end table
  961. Moreover, Org uses @i{option keywords} (like @code{#+TITLE} to set the title)
  962. and @i{environment keywords} (like @code{#+BEGIN_HTML} to start a @code{HTML}
  963. environment). They are written in uppercase in the manual to enhance its
  964. readability, but you can use lowercase in your Org files@footnote{Easy
  965. templates insert lowercase keywords and Babel dynamically inserts
  966. @code{#+results}.}
  967. @subsubheading Keybindings and commands
  968. @kindex C-c a
  969. @findex org-agenda
  970. @kindex C-c c
  971. @findex org-capture
  972. The manual suggests two global keybindings: @kbd{C-c a} for @code{org-agenda}
  973. and @kbd{C-c c} for @code{org-capture}. These are only suggestions, but the
  974. rest of the manual assumes that you are using these keybindings.
  975. Also, the manual lists both the keys and the corresponding commands for
  976. accessing a functionality. Org mode often uses the same key for different
  977. functions, depending on context. The command that is bound to such keys has
  978. a generic name, like @code{org-metaright}. In the manual we will, wherever
  979. possible, give the function that is internally called by the generic command.
  980. For example, in the chapter on document structure, @kbd{M-@key{right}} will
  981. be listed to call @code{org-do-demote}, while in the chapter on tables, it
  982. will be listed to call @code{org-table-move-column-right}. If you prefer,
  983. you can compile the manual without the command names by unsetting the flag
  984. @code{cmdnames} in @file{org.texi}.

  1007. @cindex Outline mode
  1008. Org is implemented on top of Outline mode. Outlines allow a
  1009. document to be organized in a hierarchical structure, which (at least
  1010. for me) is the best representation of notes and thoughts. An overview
  1011. of this structure is achieved by folding (hiding) large parts of the
  1012. document to show only the general document structure and the parts
  1013. currently being worked on. Org greatly simplifies the use of
  1014. outlines by compressing the entire show/hide functionality into a single
  1015. command, @command{org-cycle}, which is bound to the @key{TAB} key.

  1022. @vindex org-ctrl-k-protect-subtree
  1023. Headlines define the structure of an outline tree. The headlines in Org
  1024. start with one or more stars, on the left margin@footnote{See the variables
  1025. @code{org-special-ctrl-a/e}, @code{org-special-ctrl-k}, and
  1026. @code{org-ctrl-k-protect-subtree} to configure special behavior of @kbd{C-a},
  1027. @kbd{C-e}, and @kbd{C-k} in headlines.} @footnote{Clocking only works with
  1028. headings indented less then 30 stars.}. For example:
  1029. @example
  1030. * Top level headline
  1031. ** Second level
  1032. *** 3rd level
  1033. some text
  1034. *** 3rd level
  1035. more text
  1036. * Another top level headline
  1037. @end example
  1038. @noindent Some people find the many stars too noisy and would prefer an
  1039. outline that has whitespace followed by a single star as headline
  1040. starters. @ref{Clean view}, describes a setup to realize this.
  1041. @vindex org-cycle-separator-lines
  1042. An empty line after the end of a subtree is considered part of it and
  1043. will be hidden when the subtree is folded. However, if you leave at
  1044. least two empty lines, one empty line will remain visible after folding
  1045. the subtree, in order to structure the collapsed view. See the
  1046. variable @code{org-cycle-separator-lines} to modify this behavior.

  1072. the option @code{org-cycle-emulate-tab}.}. When the cursor is at the
  1073. beginning of the buffer and the first line is not a headline, then
  1074. @key{TAB} actually runs global cycling (see below)@footnote{see the
  1075. option @code{org-cycle-global-at-bob}.}. Also when called with a prefix

  1207. @orgcmd{M-@key{RET},org-insert-heading}
  1208. @vindex org-M-RET-may-split-line
  1209. Insert new heading with same level as current. If the cursor is in a plain
  1210. list item, a new item is created (@pxref{Plain lists}). To force creation of
  1211. a new headline, use a prefix argument. When this command is used in the
  1212. middle of a line, the line is split and the rest of the line becomes the new
  1213. headline@footnote{If you do not want the line to be split, customize the
  1214. variable @code{org-M-RET-may-split-line}.}. If the command is used at the
  1215. beginning of a headline, the new headline is created before the current line.
  1216. If at the beginning of any other line, the content of that line is made the
  1217. new heading. If the command is used at the end of a folded subtree (i.e.@:
  1218. behind the ellipses at the end of a headline), then a headline like the
  1219. current one will be inserted after the end of the subtree.
  1220. @orgcmd{C-@key{RET},org-insert-heading-respect-content}
  1221. Just like @kbd{M-@key{RET}}, except when adding a new heading below the
  1222. current heading, the new heading is placed after the body instead of before
  1223. it. This command works from anywhere in the entry.
  1224. @orgcmd{M-S-@key{RET},org-insert-todo-heading}
  1225. @vindex org-treat-insert-todo-heading-as-state-change
  1226. Insert new TODO entry with same level as current heading. See also the
  1227. variable @code{org-treat-insert-todo-heading-as-state-change}.
  1228. @orgcmd{C-S-@key{RET},org-insert-todo-heading-respect-content}
  1229. Insert new TODO entry with same level as current heading. Like
  1230. @kbd{C-@key{RET}}, the new headline will be inserted after the current
  1231. subtree.
  1232. @orgcmd{@key{TAB},org-cycle}
  1233. In a new entry with no text yet, the first @key{TAB} demotes the entry to
  1234. become a child of the previous one. The next @key{TAB} makes it a parent,
  1235. and so on, all the way to top level. Yet another @key{TAB}, and you are back
  1236. to the initial level.
  1237. @orgcmd{M-@key{left},org-do-promote}
  1238. Promote current heading by one level.
  1239. @orgcmd{M-@key{right},org-do-demote}
  1240. Demote current heading by one level.
  1241. @orgcmd{M-S-@key{left},org-promote-subtree}
  1242. Promote the current subtree by one level.
  1243. @orgcmd{M-S-@key{right},org-demote-subtree}
  1244. Demote the current subtree by one level.
  1245. @orgcmd{M-S-@key{up},org-move-subtree-up}
  1246. Move subtree up (swap with previous subtree of same
  1247. level).
  1248. @orgcmd{M-S-@key{down},org-move-subtree-down}
  1249. Move subtree down (swap with next subtree of same level).
  1250. @orgcmd{C-c C-x C-w,org-cut-subtree}
  1251. Kill subtree, i.e.@: remove it from buffer but save in kill ring.
  1252. With a numeric prefix argument N, kill N sequential subtrees.
  1253. @orgcmd{C-c C-x M-w,org-copy-subtree}
  1254. Copy subtree to kill ring. With a numeric prefix argument N, copy the N
  1255. sequential subtrees.
  1256. @orgcmd{C-c C-x C-y,org-paste-subtree}
  1257. Yank subtree from kill ring. This does modify the level of the subtree to
  1258. make sure the tree fits in nicely at the yank position. The yank level can
  1259. also be specified with a numeric prefix argument, or by yanking after a
  1260. headline marker like @samp{****}.
  1261. @orgcmd{C-y,org-yank}
  1262. @vindex org-yank-adjusted-subtrees
  1263. @vindex org-yank-folded-subtrees
  1264. Depending on the variables @code{org-yank-adjusted-subtrees} and
  1265. @code{org-yank-folded-subtrees}, Org's internal @code{yank} command will
  1266. paste subtrees folded and in a clever way, using the same command as @kbd{C-c
  1267. C-x C-y}. With the default settings, no level adjustment will take place,
  1268. but the yanked tree will be folded unless doing so would swallow text
  1269. previously visible. Any prefix argument to this command will force a normal
  1270. @code{yank} to be executed, with the prefix passed along. A good way to
  1271. force a normal yank is @kbd{C-u C-y}. If you use @code{yank-pop} after a
  1272. yank, it will yank previous kill items plainly, without adjustment and
  1273. folding.
  1274. @orgcmd{C-c C-x c,org-clone-subtree-with-time-shift}
  1275. Clone a subtree by making a number of sibling copies of it. You will be
  1276. prompted for the number of copies to make, and you can also specify if any
  1277. timestamps in the entry should be shifted. This can be useful, for example,
  1278. to create a number of tasks related to a series of lectures to prepare. For
  1279. more details, see the docstring of the command
  1280. @code{org-clone-subtree-with-time-shift}.
  1281. @orgcmd{C-c C-w,org-refile}
  1282. Refile entry or region to a different location. @xref{Refiling notes}.
  1283. @orgcmd{C-c ^,org-sort}
  1284. Sort same-level entries. When there is an active region, all entries in the
  1285. region will be sorted. Otherwise the children of the current headline are
  1286. sorted. The command prompts for the sorting method, which can be
  1287. alphabetically, numerically, by time (first timestamp with active preferred,
  1288. creation time, scheduled time, deadline time), by priority, by TODO keyword
  1289. (in the sequence the keywords have been defined in the setup) or by the value
  1290. of a property. Reverse sorting is possible as well. You can also supply
  1291. your own function to extract the sorting key. With a @kbd{C-u} prefix,
  1292. sorting will be case-sensitive.
  1293. @orgcmd{C-x n s,org-narrow-to-subtree}
  1294. Narrow buffer to current subtree.
  1295. @orgcmd{C-x n b,org-narrow-to-block}
  1296. Narrow buffer to current block.
  1297. @orgcmd{C-x n w,widen}
  1298. Widen buffer to remove narrowing.
  1299. @orgcmd{C-c *,org-toggle-heading}
  1300. Turn a normal line or plain list item into a headline (so that it becomes a
  1301. subheading at its location). Also turn a headline into a normal line by
  1302. removing the stars. If there is an active region, turn all lines in the
  1303. region into headlines. If the first line in the region was an item, turn
  1304. only the item lines into headlines. Finally, if the first line is a
  1305. headline, remove the stars from all headlines in the region.
  1306. @end table
  1307. @cindex region, active

  1309. @cindex transient mark mode
  1310. When there is an active region (Transient Mark mode), promotion and
  1311. demotion work on all headlines in the region. To select a region of
  1312. headlines, it is best to place both point and mark at the beginning of a
  1313. line, mark at the beginning of the first headline, and point at the line
  1314. just after the last headline to change. Note that when the cursor is
  1315. inside a table (@pxref{Tables}), the Meta-Cursor keys have different
  1316. functionality.

  1327. An important feature of Org mode is the ability to construct @emph{sparse
  1328. trees} for selected information in an outline tree, so that the entire
  1329. document is folded as much as possible, but the selected information is made
  1330. visible along with the headline structure above it@footnote{See also the
  1331. variables @code{org-show-hierarchy-above}, @code{org-show-following-heading},
  1332. @code{org-show-siblings}, and @code{org-show-entry-below} for detailed
  1333. control on how much context is shown around each match.}. Just try it out
  1334. and you will see immediately how it works.
  1335. Org mode contains several commands creating such trees, all these
  1336. commands can be accessed through a dispatcher:
  1337. @table @asis
  1338. @orgcmd{C-c /,org-sparse-tree}
  1339. This prompts for an extra key to select a sparse-tree creating command.
  1340. @orgcmd{C-c / r,org-occur}
  1341. @vindex org-remove-highlights-with-change
  1342. Prompts for a regexp and shows a sparse tree with all matches. If
  1343. the match is in a headline, the headline is made visible. If the match is in
  1344. the body of an entry, headline and body are made visible. In order to
  1345. provide minimal context, also the full hierarchy of headlines above the match
  1346. is shown, as well as the headline following the match. Each match is also
  1347. highlighted; the highlights disappear when the buffer is changed by an
  1348. editing command@footnote{This depends on the option
  1349. @code{org-remove-highlights-with-change}}, or by pressing @kbd{C-c C-c}.
  1350. When called with a @kbd{C-u} prefix argument, previous highlights are kept,
  1351. so several calls to this command can be stacked.
  1352. @orgcmdkkc{M-g n,M-g M-n,next-error}
  1353. Jump to the next sparse tree match in this buffer.
  1354. @orgcmdkkc{M-g p,M-g M-p,previous-error}
  1355. Jump to the previous sparse tree match in this buffer.

  1365. (setq org-agenda-custom-commands
  1366. '(("f" occur-tree "FIXME")))
  1367. @end lisp

  1377. of the document @footnote{This does not work under XEmacs, because
  1378. XEmacs uses selective display for outlining, not text properties.}.

  1398. be hard to distinguish from true headlines. In short: even though @samp{*}

  1402. @vindex org-plain-list-ordered-item-terminator
  1403. @vindex org-alphabetical-lists

  1405. a right parenthesis@footnote{You can filter out any of them by configuring
  1406. @code{org-plain-list-ordered-item-terminator}.}, such as @samp{1.} or
  1407. @samp{1)}@footnote{You can also get @samp{a.}, @samp{A.}, @samp{a)} and
  1408. @samp{A)} by configuring @code{org-alphabetical-lists}. To minimize
  1409. confusion with normal text, those are limited to one character only. Beyond
  1410. that limit, bullets will automatically fallback to numbers.}. If you want a
  1411. list to start with a different value (e.g.@: 20), start the text of the item
  1412. with @code{[@@20]}@footnote{If there's a checkbox in the item, the cookie
  1413. must be put @emph{before} the checkbox. If you have activated alphabetical
  1414. lists, you can also use counters like @code{[@@b]}.}. Those constructs can
  1415. be used in any item of the list in order to enforce a particular numbering.
  1416. @item
  1417. @emph{Description} list items are unordered list items, and contain the
  1418. separator @samp{ :: } to distinguish the description @emph{term} from the
  1419. description.
  1420. @end itemize
  1421. Items belonging to the same list must have the same indentation on the first
  1422. line. In particular, if an ordered list reaches number @samp{10.}, then the
  1423. 2--digit numbers must be written left-aligned with the other numbers in the
  1424. list. An item ends before the next line that is less or equally indented
  1425. than its bullet/number.
  1426. @vindex org-empty-line-terminates-plain-lists
  1427. A list ends whenever every item has ended, which means before any line less
  1428. or equally indented than items at top level. It also ends before two blank
  1429. lines@footnote{See also @code{org-empty-line-terminates-plain-lists}.}. In
  1430. that case, all items are closed. Here is an example:
  1431. @example
  1432. @group
  1433. ** Lord of the Rings
  1434. My favorite scenes are (in this order)
  1435. 1. The attack of the Rohirrim
  1436. 2. Eowyn's fight with the witch king
  1437. + this was already my favorite scene in the book
  1438. + I really like Miranda Otto.
  1439. 3. Peter Jackson being shot by Legolas
  1440. - on DVD only
  1441. He makes a really funny face when it happens.
  1442. But in the end, no individual scenes matter but the film as a whole.
  1443. Important actors in this film are:
  1444. - @b{Elijah Wood} :: He plays Frodo
  1445. - @b{Sean Austin} :: He plays Sam, Frodo's friend. I still remember
  1446. him very well from his role as Mikey Walsh in @i{The Goonies}.
  1447. @end group
  1448. @end example
  1449. Org supports these lists by tuning filling and wrapping commands to deal with
  1450. them correctly@footnote{Org only changes the filling settings for Emacs. For
  1451. XEmacs, you should use Kyle E. Jones' @file{filladapt.el}. To turn this on,
  1452. put into @file{.emacs}: @code{(require 'filladapt)}}, and by exporting them
  1453. properly (@pxref{Exporting}). Since indentation is what governs the
  1454. structure of these lists, many structural constructs like @code{#+BEGIN_...}
  1455. blocks can be indented to signal that they belong to a particular item.
  1456. @vindex org-list-demote-modify-bullet
  1457. @vindex org-list-indent-offset
  1458. If you find that using a different bullet for a sub-list (than that used for
  1459. the current list-level) improves readability, customize the variable
  1460. @code{org-list-demote-modify-bullet}. To get a greater difference of
  1461. indentation between items and theirs sub-items, customize
  1462. @code{org-list-indent-offset}.
  1463. @vindex org-list-automatic-rules
  1464. The following commands act on items when the cursor is in the first line of
  1465. an item (the line with the bullet or number). Some of them imply the
  1466. application of automatic rules to keep list structure intact. If some of
  1467. these actions get in your way, configure @code{org-list-automatic-rules}
  1468. to disable them individually.
  1469. @table @asis
  1470. @orgcmd{@key{TAB},org-cycle}
  1471. @cindex cycling, in plain lists
  1472. @vindex org-cycle-include-plain-lists
  1473. Items can be folded just like headline levels. Normally this works only if
  1474. the cursor is on a plain list item. For more details, see the variable
  1475. @code{org-cycle-include-plain-lists}. If this variable is set to
  1476. @code{integrate}, plain list items will be treated like low-level
  1477. headlines. The level of an item is then given by the indentation of the
  1478. bullet/number. Items are always subordinate to real headlines, however; the
  1479. hierarchies remain completely separated. In a new item with no text yet, the
  1480. first @key{TAB} demotes the item to become a child of the previous
  1481. one. Subsequent @key{TAB}s move the item to meaningful levels in the list
  1482. and eventually get it back to its initial position.
  1483. @orgcmd{M-@key{RET},org-insert-heading}
  1484. @vindex org-M-RET-may-split-line
  1485. @vindex org-list-automatic-rules
  1486. Insert new item at current level. With a prefix argument, force a new
  1487. heading (@pxref{Structure editing}). If this command is used in the middle
  1488. of an item, that item is @emph{split} in two, and the second part becomes the
  1489. new item@footnote{If you do not want the item to be split, customize the
  1490. variable @code{org-M-RET-may-split-line}.}. If this command is executed
  1491. @emph{before item's body}, the new item is created @emph{before} the current

  1507. @code{org-support-shift-select} is off. If not, you can still use paragraph
  1508. jumping commands like @kbd{C-@key{up}} and @kbd{C-@key{down}} to quite
  1509. similar effect.
  1510. @kindex M-@key{up}
  1511. @kindex M-@key{down}
  1512. @item M-up
  1513. @itemx M-down
  1514. Move the item including subitems up/down@footnote{See
  1515. @code{org-liste-use-circular-motion} for a cyclic behavior.} (swap with
  1516. previous/next item of same indentation). If the list is ordered, renumbering
  1517. is automatic.
  1518. @kindex M-@key{left}
  1519. @kindex M-@key{right}
  1520. @item M-left
  1521. @itemx M-right
  1522. Decrease/increase the indentation of an item, leaving children alone.
  1523. @kindex M-S-@key{left}
  1524. @kindex M-S-@key{right}
  1525. @item M-S-left
  1526. @itemx M-S-right
  1527. Decrease/increase the indentation of the item, including subitems.
  1528. Initially, the item tree is selected based on current indentation. When
  1529. these commands are executed several times in direct succession, the initially
  1530. selected region is used, even if the new indentation would imply a different
  1531. hierarchy. To use the new hierarchy, break the command chain with a cursor
  1532. motion or so.
  1533. As a special case, using this command on the very first item of a list will
  1534. move the whole list. This behavior can be disabled by configuring
  1535. @code{org-list-automatic-rules}. The global indentation of a list has no
  1536. influence on the text @emph{after} the list.
  1537. @kindex C-c C-c
  1538. @item C-c C-c
  1539. If there is a checkbox (@pxref{Checkboxes}) in the item line, toggle the
  1540. state of the checkbox. In any case, verify bullets and indentation
  1541. consistency in the whole list.
  1542. @kindex C-c -
  1543. @vindex org-plain-list-ordered-item-terminator
  1544. @item C-c -
  1545. Cycle the entire list level through the different itemize/enumerate bullets
  1546. (@samp{-}, @samp{+}, @samp{*}, @samp{1.}, @samp{1)}) or a subset of them,
  1547. depending on @code{org-plain-list-ordered-item-terminator}, the type of list,
  1548. and its indentation. With a numeric prefix argument N, select the Nth bullet
  1549. from this list. If there is an active region when calling this, selected
  1550. text will be changed into an item. With a prefix argument, all lines will be
  1551. converted to list items. If the first line already was a list item, any item
  1552. marker will be removed from the list. Finally, even without an active
  1553. region, a normal line will be converted into a list item.
  1554. @kindex C-c *
  1555. @item C-c *
  1556. Turn a plain list item into a headline (so that it becomes a subheading at
  1557. its location). @xref{Structure editing}, for a detailed explanation.
  1558. @kindex C-c C-*
  1559. @item C-c C-*
  1560. Turn the whole plain list into a subtree of the current heading. Checkboxes
  1561. (@pxref{Checkboxes}) will become TODO (resp. DONE) keywords when unchecked
  1562. (resp. checked).
  1563. @kindex S-@key{left}
  1564. @kindex S-@key{right}
  1565. @item S-left/right
  1566. @vindex org-support-shift-select
  1567. This command also cycles bullet styles when the cursor in on the bullet or
  1568. anywhere in an item line, details depending on
  1569. @code{org-support-shift-select}.
  1570. @kindex C-c ^
  1571. @item C-c ^
  1572. Sort the plain list. You will be prompted for the sorting method:
  1573. numerically, alphabetically, by time, or by custom function.

  1586. @code{org-drawers}@footnote{You can define additional drawers on a
  1587. per-file basis with a line like @code{#+DRAWERS: HIDDEN STATE}}. Drawers

  1593. This is inside the drawer.
  1594. :END:
  1595. After the drawer.
  1596. @end example
  1597. You can interactively insert drawers at point by calling
  1598. @code{org-insert-drawer}, which is bound to @key{C-c C-x d}. With an active
  1599. region, this command will put the region inside the drawer. With a prefix
  1600. argument, this command calls @code{org-insert-property-drawer} and add a
  1601. property drawer right below the current headline. Completion over drawer
  1602. keywords is also possible using @key{M-TAB}.
  1603. Visibility cycling (@pxref{Visibility cycling}) on the headline will hide and
  1604. show the entry, but keep the drawer collapsed to a single line. In order to
  1605. look inside the drawer, you need to move the cursor to the drawer line and
  1606. press @key{TAB} there. Org mode uses the @code{PROPERTIES} drawer for

  1635. Org mode supports the creation of footnotes. In contrast to the
  1636. @file{footnote.el} package, Org mode's footnotes are designed for work on a
  1637. larger document, not only for one-off documents like emails. The basic
  1638. syntax is similar to the one used by @file{footnote.el}, i.e.@: a footnote is
  1639. defined in a paragraph that is started by a footnote marker in square
  1640. brackets in column 0, no indentation allowed. If you need a paragraph break
  1641. inside a footnote, use the @LaTeX{} idiom @samp{\par}. The footnote reference
  1642. is simply the marker in square brackets, inside text. For example:
  1643. @example
  1644. The Org homepage[fn:1] now looks a lot better than it used to.
  1645. ...
  1646. [fn:1] The link is: http://orgmode.org
  1647. @end example
  1648. Org mode extends the number-based syntax to @emph{named} footnotes and
  1649. optional inline definition. Using plain numbers as markers (as
  1650. @file{footnote.el} does) is supported for backward compatibility, but not
  1651. encouraged because of possible conflicts with @LaTeX{} snippets (@pxref{Embedded
  1652. @LaTeX{}}). Here are the valid references:
  1653. @table @code
  1654. @item [1]
  1655. A plain numeric footnote marker. Compatible with @file{footnote.el}, but not
  1656. recommended because something like @samp{[1]} could easily be part of a code
  1657. snippet.
  1658. @item [fn:name]
  1659. A named footnote reference, where @code{name} is a unique label word, or, for
  1660. simplicity of automatic creation, a number.
  1661. @item [fn:: This is the inline definition of this footnote]
  1662. A @LaTeX{}-like anonymous footnote where the definition is given directly at the
  1663. reference point.
  1664. @item [fn:name: a definition]
  1665. An inline definition of a footnote, which also specifies a name for the note.
  1666. Since Org allows multiple references to the same note, you can then use
  1667. @code{[fn:name]} to create additional references.
  1668. @end table
  1669. @vindex org-footnote-auto-label
  1670. Footnote labels can be created automatically, or you can create names yourself.
  1671. This is handled by the variable @code{org-footnote-auto-label} and its
  1672. corresponding @code{#+STARTUP} keywords. See the docstring of that variable
  1673. for details.
  1674. @noindent The following command handles footnotes:
  1675. @table @kbd
  1676. @kindex C-c C-x f
  1677. @item C-c C-x f
  1678. The footnote action command.
  1679. When the cursor is on a footnote reference, jump to the definition. When it
  1680. is at a definition, jump to the (first) reference.
  1681. @vindex org-footnote-define-inline
  1682. @vindex org-footnote-section
  1683. @vindex org-footnote-auto-adjust

  1685. @code{org-footnote-define-inline}@footnote{The corresponding in-buffer
  1686. setting is: @code{#+STARTUP: fninline} or @code{#+STARTUP: nofninline}}, the
  1687. definition will be placed right into the text as part of the reference, or
  1688. separately into the location determined by the variable
  1689. @code{org-footnote-section}.
  1690. When this command is called with a prefix argument, a menu of additional
  1691. options is offered:
  1692. @example
  1693. s @r{Sort the footnote definitions by reference sequence. During editing,}
  1694. @r{Org makes no effort to sort footnote definitions into a particular}
  1695. @r{sequence. If you want them sorted, use this command, which will}

  1732. If you like the intuitive way the Org mode structure editing and list
  1733. formatting works, you might want to use these commands in other modes like
  1734. Text mode or Mail mode as well. The minor mode @code{orgstruct-mode} makes
  1735. this possible. Toggle the mode with @kbd{M-x orgstruct-mode}, or
  1736. turn it on by default, for example in Message mode, with one of:
  1737. @lisp
  1738. (add-hook 'message-mode-hook 'turn-on-orgstruct)
  1739. (add-hook 'message-mode-hook 'turn-on-orgstruct++)
  1740. @end lisp
  1741. When this mode is active and the cursor is on a line that looks to Org like a
  1742. headline or the first line of a list item, most structure editing commands
  1743. will work, even if the same keys normally have different functionality in the
  1744. major mode you are using. If the cursor is not in one of those special
  1745. lines, Orgstruct mode lurks silently in the shadows. When you use
  1746. @code{orgstruct++-mode}, Org will also export indentation and autofill
  1747. settings into that mode, and detect item context after the first line of an
  1748. item.

  1768. the first non-whitespace character is considered part of a table. @samp{|}
  1769. is also the column separator@footnote{To insert a vertical bar into a table
  1770. field, use @code{\vert} or, inside a word @code{abc\vert@{@}def}.}. A table
  1771. might look like this:
  1772. @example
  1773. | Name | Phone | Age |
  1774. |-------+-------+-----|
  1775. | Peter | 1234 | 17 |
  1776. | Anna | 4321 | 25 |
  1777. @end example
  1778. A table is re-aligned automatically each time you press @key{TAB} or
  1779. @key{RET} or @kbd{C-c C-c} inside the table. @key{TAB} also moves to
  1780. the next field (@key{RET} to the next row) and creates new table rows
  1781. at the end of the table or before horizontal lines. The indentation
  1782. of the table is set by the first line. Any line starting with
  1783. @samp{|-} is considered as a horizontal separator line and will be
  1784. expanded on the next re-align to span the whole table width. So, to
  1785. create the above table, you would only type
  1786. @example
  1787. |Name|Phone|Age|
  1788. |-
  1789. @end example
  1790. @noindent and then press @key{TAB} to align the table and start filling in

  1795. When typing text into a field, Org treats @key{DEL},
  1796. @key{Backspace}, and all character keys in a special way, so that
  1797. inserting and deleting avoids shifting other fields. Also, when
  1798. typing @emph{immediately after the cursor was moved into a new field
  1799. with @kbd{@key{TAB}}, @kbd{S-@key{TAB}} or @kbd{@key{RET}}}, the
  1800. field is automatically made blank. If this behavior is too
  1801. unpredictable for you, configure the variables
  1802. @code{org-enable-table-editor} and @code{org-table-auto-blank-field}.
  1803. @table @kbd
  1804. @tsubheading{Creation and conversion}
  1805. @orgcmd{C-c |,org-table-create-or-convert-from-region}
  1806. Convert the active region to table. If every line contains at least one
  1807. TAB character, the function assumes that the material is tab separated.
  1808. If every line contains a comma, comma-separated values (CSV) are assumed.
  1809. If not, lines are split at whitespace into fields. You can use a prefix
  1810. argument to force a specific separator: @kbd{C-u} forces CSV, @kbd{C-u
  1811. C-u} forces TAB, and a numeric argument N indicates that at least N
  1812. consecutive spaces, or alternatively a TAB will be the separator.
  1813. @*
  1814. If there is no active region, this command creates an empty Org
  1815. table. But it is easier just to start typing, like

  1866. Sort the table lines in the region. The position of point indicates the
  1867. column to be used for sorting, and the range of lines is the range
  1868. between the nearest horizontal separator lines, or the entire table. If
  1869. point is before the first column, you will be prompted for the sorting
  1870. column. If there is an active region, the mark specifies the first line
  1871. and the sorting column, while point should be in the last line to be
  1872. included into the sorting. The command prompts for the sorting type
  1873. (alphabetically, numerically, or by time). When called with a prefix
  1874. argument, alphabetic sorting will be case-sensitive.
  1875. @tsubheading{Regions}
  1876. @orgcmd{C-c C-x M-w,org-table-copy-region}
  1877. Copy a rectangular region from a table to a special clipboard. Point and

  1879. copy just the current field. The process ignores horizontal separator lines.
  1880. @c
  1881. @orgcmd{C-c C-x C-w,org-table-cut-region}

  1884. @c
  1885. @orgcmd{C-c C-x C-y,org-table-paste-rectangle}
  1886. Paste a rectangular region into a table.
  1887. The upper left corner ends up in the current field. All involved fields
  1888. will be overwritten. If the rectangle does not fit into the present table,
  1889. the table is enlarged as needed. The process ignores horizontal separator
  1890. lines.
  1891. @c
  1892. @orgcmd{M-@key{RET},org-table-wrap-region}
  1893. Split the current field at the cursor position and move the rest to the line
  1894. below. If there is an active region, and both point and mark are in the same
  1895. column, the text in the column is wrapped to minimum width for the given
  1896. number of lines. A numeric prefix argument may be used to change the number
  1897. of desired lines. If there is no region, but you specify a prefix argument,
  1898. the current field is made blank, and the content is appended to the field
  1899. above.

  1906. @orgcmd{C-c +,org-table-sum}
  1907. Sum the numbers in the current column, or in the rectangle defined by
  1908. the active region. The result is shown in the echo area and can
  1909. be inserted with @kbd{C-y}.
  1910. @c
  1911. @orgcmd{S-@key{RET},org-table-copy-down}
  1912. @vindex org-table-copy-increment
  1913. When current field is empty, copy from first non-empty field above. When not
  1914. empty, copy current field down to next row and move cursor along with it.
  1915. Depending on the variable @code{org-table-copy-increment}, integer field
  1916. values will be incremented during copy. Integers that are too large will not
  1917. be incremented. Also, a @code{0} prefix argument temporarily disables the
  1918. increment. This key is also used by shift-selection and related modes
  1919. (@pxref{Conflicts}).
  1920. @tsubheading{Miscellaneous}
  1921. @orgcmd{C-c `,org-table-edit-field}
  1922. Edit the current field in a separate window. This is useful for fields that
  1923. are not fully visible (@pxref{Column width and alignment}). When called with
  1924. a @kbd{C-u} prefix, just make the full field visible, so that it can be
  1925. edited in place. When called with two @kbd{C-u} prefixes, make the editor
  1926. window follow the cursor through the table and always show the current
  1927. field. The follow mode exits automatically when the cursor leaves the table,
  1928. or when you repeat this command with @kbd{C-u C-u C-c `}.
  1929. @c
  1930. @item M-x org-table-import
  1931. Import a file as a table. The table should be TAB or whitespace
  1932. separated. Use, for example, to import a spreadsheet table or data
  1933. from a database, because these programs generally can write
  1934. TAB-separated text files. This command works by inserting the file into
  1935. the buffer and then converting the region to a table. Any prefix
  1936. argument is passed on to the converter, which uses it to determine the
  1937. separator.
  1938. @orgcmd{C-c |,org-table-create-or-convert-from-region}
  1939. Tables can also be imported by pasting tabular text into the Org
  1940. buffer, selecting the pasted text with @kbd{C-x C-x} and then using the
  1941. @kbd{C-c |} command (see above under @i{Creation and conversion}).
  1942. @c
  1943. @item M-x org-table-export
  1944. @findex org-table-export
  1945. @vindex org-table-export-default-format
  1946. Export the table, by default as a TAB-separated file. Use for data
  1947. exchange with, for example, spreadsheet or database programs. The format
  1948. used to export the file can be configured in the variable
  1949. @code{org-table-export-default-format}. You may also use properties
  1950. @code{TABLE_EXPORT_FILE} and @code{TABLE_EXPORT_FORMAT} to specify the file
  1951. name and the format for table export in a subtree. Org supports quite
  1952. general formats for exported tables. The exporter format is the same as the
  1953. format used by Orgtbl radio tables, see @ref{Translator functions}, for a
  1954. detailed description.
  1955. @end table
  1956. If you don't like the automatic table editor because it gets in your
  1957. way on lines which you would like to start with @samp{|}, you can turn
  1958. it off with
  1959. @lisp
  1960. (setq org-enable-table-editor nil)
  1961. @end lisp
  1962. @noindent Then the only table command that still works is
  1963. @kbd{C-c C-c} to do a manual re-align.

  1966. @cindex narrow columns in tables
  1967. @cindex alignment in tables
  1968. The width of columns is automatically determined by the table editor. And
  1969. also the alignment of a column is determined automatically from the fraction
  1970. of number-like versus non-number fields in the column.
  1971. Sometimes a single field or a few fields need to carry more text, leading to
  1972. inconveniently wide columns. Or maybe you want to make a table with several
  1973. columns having a fixed width, regardless of content. To set@footnote{This
  1974. feature does not work on XEmacs.} the width of a column, one field anywhere
  1975. in the column may contain just the string @samp{<N>} where @samp{N} is an
  1976. integer specifying the width of the column in characters. The next re-align
  1977. will then set the width of this column to this value.
  1978. @example
  1979. @group
  1980. |---+------------------------------| |---+--------|
  1981. | | | | | <6> |
  1982. | 1 | one | | 1 | one |
  1983. | 2 | two | ----\ | 2 | two |
  1984. | 3 | This is a long chunk of text | ----/ | 3 | This=> |
  1985. | 4 | four | | 4 | four |
  1986. |---+------------------------------| |---+--------|
  1987. @end group
  1988. @end example
  1989. @noindent
  1990. Fields that are wider become clipped and end in the string @samp{=>}.
  1991. Note that the full text is still in the buffer but is hidden.
  1992. To see the full text, hold the mouse over the field---a tool-tip window
  1993. will show the full content. To edit such a field, use the command
  1994. @kbd{C-c `} (that is @kbd{C-c} followed by the backquote). This will
  1995. open a new window with the full field. Edit it and finish with @kbd{C-c
  1996. C-c}.
  1997. @vindex org-startup-align-all-tables
  1998. When visiting a file containing a table with narrowed columns, the
  1999. necessary character hiding has not yet happened, and the table needs to
  2000. be aligned before it looks nice. Setting the option
  2001. @code{org-startup-align-all-tables} will realign all tables in a file
  2002. upon visiting, but also slow down startup. You can also set this option
  2003. on a per-file basis with:
  2004. @example
  2005. #+STARTUP: align
  2006. #+STARTUP: noalign
  2007. @end example
  2008. If you would like to overrule the automatic alignment of number-rich columns
  2009. to the right and of string-rich column to the left, you can use @samp{<r>},
  2010. @samp{<c>}@footnote{Centering does not work inside Emacs, but it does have an
  2011. effect when exporting to HTML.} or @samp{<l>} in a similar fashion. You may
  2012. also combine alignment and field width like this: @samp{<l10>}.
  2013. Lines which only contain these formatting cookies will be removed
  2014. automatically when exporting the document.
  2015. @node Column groups, Orgtbl mode, Column width and alignment, Tables
  2016. @section Column groups
  2017. @cindex grouping columns in tables
  2018. When Org exports tables, it does so by default without vertical
  2019. lines because that is visually more satisfying in general. Occasionally
  2020. however, vertical lines can be useful to structure a table into groups
  2021. of columns, much like horizontal lines can do for groups of rows. In
  2022. order to specify column groups, you can use a special row where the
  2023. first field contains only @samp{/}. The further fields can either
  2024. contain @samp{<} to indicate that this column should start a group,
  2025. @samp{>} to indicate the end of a column, or @samp{<>} (no space between @samp{<}
  2026. and @samp{>}) to make a column
  2027. a group of its own. Boundaries between column groups will upon export be
  2028. marked with vertical lines. Here is an example:
  2029. @example
  2030. | N | N^2 | N^3 | N^4 | sqrt(n) | sqrt[4](N) |
  2031. |---+-----+-----+-----+---------+------------|
  2032. | / | < | | > | < | > |
  2033. | 1 | 1 | 1 | 1 | 1 | 1 |
  2034. | 2 | 4 | 8 | 16 | 1.4142 | 1.1892 |
  2035. | 3 | 9 | 27 | 81 | 1.7321 | 1.3161 |
  2036. |---+-----+-----+-----+---------+------------|
  2037. #+TBLFM: $2=$1^2::$3=$1^3::$4=$1^4::$5=sqrt($1)::$6=sqrt(sqrt(($1)))
  2038. @end example
  2039. It is also sufficient to just insert the column group starters after
  2040. every vertical line you would like to have:
  2041. @example
  2042. | N | N^2 | N^3 | N^4 | sqrt(n) | sqrt[4](N) |

  2052. The minor mode Orgtbl mode makes this possible. You can always toggle

  2056. (add-hook 'message-mode-hook 'turn-on-orgtbl)
  2057. @end lisp
  2058. Furthermore, with some special setup, it is possible to maintain tables
  2059. in arbitrary syntax with Orgtbl mode. For example, it is possible to
  2060. construct @LaTeX{} tables with the underlying ease and power of
  2061. Orgtbl mode, including spreadsheet capabilities. For details, see

  2072. of a @emph{column formula} that will be applied to all non-header fields in a
  2073. column without having to copy the formula to each relevant field. There is
  2074. also a formula debugger, and a formula editor with features for highlighting

  2091. To compute fields in the table from other fields, formulas must
  2092. reference other fields or ranges. In Org, fields can be referenced
  2093. by name, by absolute coordinates, and by relative coordinates. To find
  2094. out what the coordinates of a field are, press @kbd{C-c ?} in that
  2095. field, or press @kbd{C-c @}} to toggle the display of a grid.
  2096. @subsubheading Field references

  2098. @cindex references, to fields
  2099. Formulas can reference the value of another field in two ways. Like in
  2100. any other spreadsheet, you may reference fields with a letter/number
  2101. combination like @code{B3}, meaning the 2nd field in the 3rd row.
  2102. @vindex org-table-use-standard-references
  2103. However, Org prefers@footnote{Org will understand references typed by the
  2104. user as @samp{B4}, but it will not use this syntax when offering a formula
  2105. for editing. You can customize this behavior using the variable
  2106. @code{org-table-use-standard-references}.} to use another, more general
  2107. representation that looks like this:
  2108. @example
  2109. @@@var{row}$@var{column}
  2110. @end example
  2111. Column specifications can be absolute like @code{$1},
  2112. @code{$2},...@code{$@var{N}}, or relative to the current column (i.e.@: the
  2113. column of the field which is being computed) like @code{$+1} or @code{$-2}.
  2114. @code{$<} and @code{$>} are immutable references to the first and last
  2115. column, respectively, and you can use @code{$>>>} to indicate the third
  2116. column from the right.
  2117. The row specification only counts data lines and ignores horizontal separator
  2118. lines (hlines). Like with columns, you can use absolute row numbers
  2119. @code{@@1}, @code{@@2},...@code{@@@var{N}}, and row numbers relative to the
  2120. current row like @code{@@+3} or @code{@@-1}. @code{@@<} and @code{@@>} are
  2121. immutable references the first and last@footnote{For backward compatibility
  2122. you can also use special names like @code{$LR5} and @code{$LR12} to refer in
  2123. a stable way to the 5th and 12th field in the last row of the table.
  2124. However, this syntax is deprecated, it should not be used for new documents.
  2125. Use @code{@@>$} instead.} row in the table, respectively. You may also
  2126. specify the row relative to one of the hlines: @code{@@I} refers to the first
  2127. hline, @code{@@II} to the second, etc@. @code{@@-I} refers to the first such
  2128. line above the current line, @code{@@+I} to the first such line below the
  2129. current line. You can also write @code{@@III+2} which is the second data line
  2130. after the third hline in the table.
  2131. @code{@@0} and @code{$0} refer to the current row and column, respectively,
  2132. i.e. to the row/column for the field being computed. Also, if you omit
  2133. either the column or the row part of the reference, the current row/column is
  2134. implied.
  2135. Org's references with @emph{unsigned} numbers are fixed references
  2136. in the sense that if you use the same reference in the formula for two
  2137. different fields, the same field will be referenced each time.
  2138. Org's references with @emph{signed} numbers are floating
  2139. references because the same reference operator can reference different
  2140. fields depending on the field being calculated by the formula.
  2141. Here are a few examples:
  2142. @example
  2143. @@2$3 @r{2nd row, 3rd column (same as @code{C2})}

  2155. current row, you may simply use @samp{$2..$7}, but if at least one field
  2156. is in a different row, you need to use the general @code{@@row$column}
  2157. format at least for the first field (i.e the reference must start with
  2158. @samp{@@} in order to be interpreted correctly). Examples:
  2159. @example

  2167. @noindent Range references return a vector of values that can be fed
  2168. into Calc vector functions. Empty fields in ranges are normally
  2169. suppressed, so that the vector contains only the non-empty fields (but

  2279. Unless you use large integer numbers or high-precision-calculation
  2280. and -display for floating point numbers you may alternatively provide a
  2281. @code{printf} format specifier to reformat the Calc result after it has been
  2282. passed back to Org instead of letting Calc already do the
  2283. formatting@footnote{The @code{printf} reformatting is limited in precision
  2284. because the value passed to it is converted into an @code{integer} or
  2285. @code{double}. The @code{integer} is limited in size by truncating the
  2286. signed value to 32 bits. The @code{double} is limited in precision to 64
  2287. bits overall which leaves approximately 16 significant decimal digits.}.
  2288. A few examples:
  2289. @example
  2290. $1+$2 @r{Sum of first and second field}
  2291. $1+$2;%.2f @r{Same, format result to two decimals}
  2292. exp($2)+exp($1) @r{Math functions can be used}
  2293. $0;%.1f @r{Reformat current cell to 1 decimal}
  2294. ($3-32)*5/9 @r{Degrees F -> C conversion}
  2295. $c/$1/$cm @r{Hz -> cm conversion, using @file{constants.el}}
  2296. tan($1);Dp3s1 @r{Compute in degrees, precision 3, display SCI 1}

  2301. @end example
  2302. Calc also contains a complete set of logical operations. For example
  2303. @example
  2304. if($1<20,teen,string("")) @r{"teen" if age $1 less than 20, else empty}
  2305. @end example
  2306. Note that you can also use two org-specific flags @code{T} and @code{t} for
  2307. durations computations @ref{Durations and time values}.

  2309. @subsection Emacs Lisp forms as formulas
  2310. @cindex Lisp forms, as table formulas
  2311. It is also possible to write a formula in Emacs Lisp. This can be useful
  2312. for string manipulation and control structures, if Calc's functionality is
  2313. not enough.
  2314. If a formula starts with a single-quote followed by an opening parenthesis,
  2315. then it is evaluated as a Lisp form. The evaluation should return either a
  2316. string or a number. Just as with @file{calc} formulas, you can specify modes
  2317. and a printf format after a semicolon.
  2318. With Emacs Lisp forms, you need to be conscious about the way field
  2319. references are interpolated into the form. By default, a reference will be
  2320. interpolated as a Lisp string (in double-quotes) containing the field. If
  2321. you provide the @samp{N} mode switch, all referenced elements will be numbers
  2322. (non-number fields will be zero) and interpolated as Lisp numbers, without
  2323. quotes. If you provide the @samp{L} flag, all fields will be interpolated
  2324. literally, without quotes. I.e., if you want a reference to be interpreted
  2325. as a string by the Lisp form, enclose the reference operator itself in
  2326. double-quotes, like @code{"$3"}. Ranges are inserted as space-separated
  2327. fields, so you can embed them in list or vector syntax.
  2328. Here are a few examples---note how the @samp{N} mode is used when we do
  2329. computations in Lisp:
  2330. @example
  2331. @r{Swap the first two characters of the content of column 1}
  2332. '(concat (substring $1 1 2) (substring $1 0 1) (substring $1 2))
  2333. @r{Add columns 1 and 2, equivalent to Calc's @code{$1+$2}}
  2334. '(+ $1 $2);N
  2335. @r{Compute the sum of columns 1-4, like Calc's @code{vsum($1..$4)}}
  2336. '(apply '+ '($1..$4));N

  2354. Input duration values must be of the form @code{[HH:MM[:SS]}, where seconds
  2355. are optional. With the @code{T} flag, computed durations will be displayed
  2356. as @code{HH:MM:SS} (see the first formula above). With the @code{t} flag,
  2357. computed durations will be displayed according to the value of the variable
  2358. @code{org-table-duration-custom-format}, which defaults to @code{'hours} and
  2359. will display the result as a fraction of hours (see the second formula in the
  2360. example above).
  2361. Negative duration values can be manipulated as well, and integers will be
  2362. considered as seconds in addition and subtraction.

  2371. @key{TAB} or @key{RET} or @kbd{C-c C-c} with the cursor still in the field,
  2372. the formula will be stored as the formula for this field, evaluated, and the
  2373. current field will be replaced with the result.
  2374. @cindex #+TBLFM
  2375. Formulas are stored in a special line starting with @samp{#+TBLFM:} directly
  2376. below the table. If you type the equation in the 4th field of the 3rd data
  2377. line in the table, the formula will look like @samp{@@3$4=$1+$2}. When
  2378. inserting/deleting/swapping column and rows with the appropriate commands,
  2379. @i{absolute references} (but not relative ones) in stored formulas are
  2380. modified in order to still reference the same field. To avoid this from
  2381. happening, in particular in range references, anchor ranges at the table
  2382. borders (using @code{@@<}, @code{@@>}, @code{$<}, @code{$>}), or at hlines
  2383. using the @code{@@I} notation. Automatic adaptation of field references does
  2384. of course not happen if you edit the table structure with normal editing
  2385. commands---then you must fix the equations yourself.
  2386. Instead of typing an equation into the field, you may also use the following
  2387. command
  2388. @table @kbd
  2389. @orgcmd{C-u C-c =,org-table-eval-formula}
  2390. Install a new formula for the current field. The command prompts for a
  2391. formula with default taken from the @samp{#+TBLFM:} line, applies
  2392. it to the current field, and stores it.
  2393. @end table
  2394. The left-hand side of a formula can also be a special expression in order to

  2418. very convenient exceptions: (i) If the table contains horizontal separator
  2419. hlines, everything before the first such line is considered part of the table
  2420. @emph{header} and will not be modified by column formulas. (ii) Fields that
  2421. already get a value from a field/range formula will be left alone by column
  2422. formulas. These conditions make column formulas very easy to use.
  2423. To assign a formula to a column, type it directly into any field in the
  2424. column, preceded by an equal sign, like @samp{=$1+$2}. When you press
  2425. @key{TAB} or @key{RET} or @kbd{C-c C-c} with the cursor still in the field,
  2426. the formula will be stored as the formula for the current column, evaluated
  2427. and the current field replaced with the result. If the field contains only
  2428. @samp{=}, the previously stored formula for this column is used. For each
  2429. column, Org will only remember the most recently used formula. In the
  2430. @samp{#+TBLFM:} line, column formulas will look like @samp{$4=$1+$2}. The
  2431. left-hand side of a column formula can not be the name of column, it must be

  2436. @orgcmd{C-c =,org-table-eval-formula}
  2437. Install a new formula for the current column and replace current field with

  2632. Parameters work exactly like constants, only that they can be defined on
  2633. a per-table basis.

  2635. Fields in this row are automatically recalculated when pressing
  2636. @key{TAB} or @key{RET} or @kbd{S-@key{TAB}} in this row. Also, this row
  2637. is selected for a global recalculation with @kbd{C-u C-c *}. Unmarked
  2638. lines will be left alone by this command.
  2639. @item *
  2640. Selects this line for global recalculation with @kbd{C-u C-c *}, but
  2641. not for automatic recalculation. Use this when automatic
  2642. recalculation slows down editing too much.
  2643. @item
  2644. Unmarked lines are exempt from recalculation with @kbd{C-u C-c *}.
  2645. All lines that should be recalculated should be marked with @samp{#}
  2646. or @samp{*}.
  2647. @item /
  2648. Do not export this line. Useful for lines that contain the narrowing
  2649. @samp{<N>} markers or column group markers.

  2757. Org will recognize plain URL-like links and activate them as
  2758. clickable links. The general link format, however, looks like this:
  2759. @example
  2760. [[link][description]] @r{or alternatively} [[link]]
  2761. @end example
  2762. @noindent
  2763. Once a link in the buffer is complete (all brackets present), Org
  2764. will change the display so that @samp{description} is displayed instead
  2765. of @samp{[[link][description]]} and @samp{link} is displayed instead of
  2766. @samp{[[link]]}. Links will be highlighted in the face @code{org-link},
  2767. which by default is an underlined face. You can directly edit the
  2768. visible part of a link. Note that this can be either the @samp{link}
  2769. part (if there is no description) or the @samp{description} part. To
  2770. edit also the invisible @samp{link} part, use @kbd{C-c C-l} with the
  2771. cursor on the link.
  2772. If you place the cursor at the beginning or just behind the end of the
  2773. displayed text and press @key{BACKSPACE}, you will remove the
  2774. (invisible) bracket at that location. This makes the link incomplete
  2775. and the internals are again displayed as plain text. Inserting the
  2776. missing bracket hides the link internals again. To show the
  2777. internal structure of all links, use the menu entry

  2785. If the link does not look like a URL, it is considered to be internal in the
  2786. current file. The most important case is a link like
  2787. @samp{[[#my-custom-id]]} which will link to the entry with the
  2788. @code{CUSTOM_ID} property @samp{my-custom-id}. Such custom IDs are very good
  2789. for HTML export (@pxref{HTML export}) where they produce pretty section
  2790. links. You are responsible yourself to make sure these custom IDs are unique
  2791. in a file.
  2792. Links such as @samp{[[My Target]]} or @samp{[[My Target][Find my target]]}
  2793. lead to a text search in the current file.
  2794. The link can be followed with @kbd{C-c C-o} when the cursor is on the link,
  2795. or with a mouse click (@pxref{Handling links}). Links to custom IDs will
  2796. point to the corresponding headline. The preferred match for a text link is
  2797. a @i{dedicated target}: the same string in double angular brackets. Targets
  2798. may be located anywhere; sometimes it is convenient to put them into a
  2799. comment line. For example
  2800. @example
  2801. # <<My Target>>
  2802. @end example
  2803. @noindent In HTML export (@pxref{HTML export}), such targets will become
  2804. named anchors for direct access through @samp{http} links@footnote{Note that
  2805. text before the first headline is usually not exported, so the first such
  2806. target should be after the first headline, or in the line directly before the
  2807. first headline.}.
  2808. If no dedicated target exists, Org will search for a headline that is exactly
  2809. the link text but may also include a TODO keyword and tags@footnote{To insert
  2810. a link targeting a headline, in-buffer completion can be used. Just type a
  2811. star followed by a few optional letters into the buffer and press
  2812. @kbd{M-@key{TAB}}. All headlines in the current buffer will be offered as
  2813. completions.}. In non-Org files, the search will look for the words in the
  2814. link text. In the above example the search would be for @samp{my target}.
  2815. Following a link pushes a mark onto Org's own mark ring. You can
  2816. return to the previous position with @kbd{C-c &}. Using this command
  2817. several times in direct succession goes back to positions recorded
  2818. earlier.

  2827. Org can automatically turn any occurrences of certain target names
  2828. in normal text into a link. So without explicitly creating a link, the
  2829. text connects to the target radioing its position. Radio targets are
  2830. enclosed by triple angular brackets. For example, a target @samp{<<<My
  2831. Target>>>} causes each occurrence of @samp{my target} in normal text to
  2832. become activated as a link. The Org file is scanned automatically
  2833. for radio targets only when the file is first loaded into Emacs. To
  2834. update the target list during editing, press @kbd{C-c C-c} with the
  2835. cursor on or at a target.

  2905. A link should be enclosed in double brackets and may contain a

  2910. @end example
  2911. @noindent
  2912. If the description is a file name or URL that points to an image, HTML
  2913. export (@pxref{HTML export}) will inline the image as a clickable
  2914. button. If there is no description at all and the link points to an
  2915. image,
  2916. that image will be inlined into the exported HTML file.
  2917. @cindex square brackets, around links
  2918. @cindex plain text external links
  2919. Org also finds external links in the normal text and activates them
  2920. as links. If spaces must be part of the link (for example in
  2921. @samp{bbdb:Richard Stallman}), or if you need to remove ambiguities
  2922. about the end of the link, enclose them in square brackets.

  2926. Org provides methods to create a link in the correct syntax, to
  2927. insert it into an Org file, and to follow the link.
  2928. @table @kbd
  2929. @orgcmd{C-c l,org-store-link}
  2930. @cindex storing links
  2931. Store a link to the current location. This is a @emph{global} command (you
  2932. must create the key binding yourself) which can be used in any buffer to
  2933. create a link. The link will be stored for later insertion into an Org
  2934. buffer (see below). What kind of link will be created depends on the current
  2935. buffer:
  2936. @b{Org mode buffers}@*
  2937. For Org files, if there is a @samp{<<target>>} at the cursor, the link points
  2938. to the target. Otherwise it points to the current headline, which will also
  2939. be the description@footnote{If the headline contains a timestamp, it will be
  2940. removed from the link and result in a wrong link -- you should avoid putting
  2941. timestamp in the headline.}.
  2942. @vindex org-link-to-org-use-id
  2943. @cindex property, CUSTOM_ID
  2944. @cindex property, ID
  2945. If the headline has a @code{CUSTOM_ID} property, a link to this custom ID
  2946. will be stored. In addition or alternatively (depending on the value of
  2947. @code{org-link-to-org-use-id}), a globally unique @code{ID} property will be
  2948. created and/or used to construct a link. So using this command in Org
  2949. buffers will potentially create two links: a human-readable from the custom
  2950. ID, and one that is globally unique and works even if the entry is moved from
  2951. file to file. Later, when inserting the link, you need to decide which one
  2952. to use.
  2953. @b{Email/News clients: VM, Rmail, Wanderlust, MH-E, Gnus}@*
  2954. Pretty much all Emacs mail clients are supported. The link will point to the
  2955. current article, or, in some GNUS buffers, to the group. The description is
  2956. constructed from the author and the subject.
  2957. @b{Web browsers: W3 and W3M}@*
  2958. Here the link will be the current URL, with the page title as description.
  2959. @b{Contacts: BBDB}@*
  2960. Links created in a BBDB buffer will point to the current entry.
  2961. @b{Chat: IRC}@*
  2962. @vindex org-irc-link-to-logs
  2963. For IRC links, if you set the variable @code{org-irc-link-to-logs} to
  2964. @code{t}, a @samp{file:/} style link to the relevant point in the logs for
  2965. the current conversation is created. Otherwise an @samp{irc:/} style link to
  2966. the user/channel/server under the point will be stored.
  2967. @b{Other files}@*
  2968. For any other files, the link will point to the file, with a search string
  2969. (@pxref{Search options}) pointing to the contents of the current line. If
  2970. there is an active region, the selected words will form the basis of the
  2971. search string. If the automatically created link is not working correctly or
  2972. accurately enough, you can write custom functions to select the search string
  2973. and to do the search for particular file types---see @ref{Custom searches}.
  2974. The key binding @kbd{C-c l} is only a suggestion---see @ref{Installation}.
  2975. @b{Agenda view}@*
  2976. When the cursor is in an agenda view, the created link points to the
  2977. entry referenced by the current line.
  2978. @c
  2979. @orgcmd{C-c C-l,org-insert-link}
  2980. @cindex link completion
  2981. @cindex completion, of links
  2982. @cindex inserting links
  2983. @vindex org-keep-stored-link-after-insertion
  2984. Insert a link@footnote{ Note that you don't have to use this command to
  2985. insert a link. Links in Org are plain text, and you can type or paste them
  2986. straight into the buffer. By using this command, the links are automatically
  2987. enclosed in double brackets, and you will be asked for the optional
  2988. descriptive text.}. This prompts for a link to be inserted into the buffer.
  2989. You can just type a link, using text for an internal link, or one of the link
  2990. type prefixes mentioned in the examples above. The link will be inserted
  2991. into the buffer@footnote{After insertion of a stored link, the link will be
  2992. removed from the list of stored links. To keep it in the list later use, use
  2993. a triple @kbd{C-u} prefix argument to @kbd{C-c C-l}, or configure the option
  2994. @code{org-keep-stored-link-after-insertion}.}, along with a descriptive text.
  2995. If some text was selected when this command is called, the selected text
  2996. becomes the default description.
  2997. @b{Inserting stored links}@*
  2998. All links stored during the
  2999. current session are part of the history for this prompt, so you can access
  3000. them with @key{up} and @key{down} (or @kbd{M-p/n}).
  3001. @b{Completion support}@* Completion with @key{TAB} will help you to insert
  3002. valid link prefixes like @samp{http:} or @samp{ftp:}, including the prefixes

  3004. press @key{RET} after inserting only the @var{prefix}, Org will offer
  3005. specific completion support for some link types@footnote{This works by
  3006. calling a special function @code{org-PREFIX-complete-link}.} For
  3007. example, if you type @kbd{file @key{RET}}, file name completion (alternative
  3008. access: @kbd{C-u C-c C-l}, see below) will be offered, and after @kbd{bbdb

  3010. @orgkey C-u C-c C-l
  3011. @cindex file name completion
  3012. @cindex completion, of file names
  3013. When @kbd{C-c C-l} is called with a @kbd{C-u} prefix argument, a link to
  3014. a file will be inserted and you may use file name completion to select
  3015. the name of the file. The path to the file is inserted relative to the
  3016. directory of the current Org file, if the linked file is in the current
  3017. directory or in a sub-directory of it, or if the path is written relative
  3018. to the current directory using @samp{../}. Otherwise an absolute path
  3019. is used, if possible with @samp{~/} for your home directory. You can
  3020. force an absolute path with two @kbd{C-u} prefixes.
  3021. @c
  3022. @item C-c C-l @ @r{(with cursor on existing link)}
  3023. When the cursor is on an existing link, @kbd{C-c C-l} allows you to edit the
  3024. link and description parts of the link.

  3030. Open link at point. This will launch a web browser for URLs (using
  3031. @command{browse-url-at-point}), run VM/MH-E/Wanderlust/Rmail/Gnus/BBDB for
  3032. the corresponding links, and execute the command in a shell link. When the
  3033. cursor is on an internal link, this command runs the corresponding search.
  3034. When the cursor is on a TAG list in a headline, it creates the corresponding
  3035. TAGS view. If the cursor is on a timestamp, it compiles the agenda for that
  3036. date. Furthermore, it will visit text and remote files in @samp{file:} links
  3037. with Emacs and select a suitable application for local non-text files.
  3038. Classification of files is based on file extension only. See option
  3039. @code{org-file-apps}. If you want to override the default application and
  3040. visit the file with Emacs, use a @kbd{C-u} prefix. If you want to avoid
  3041. opening in Emacs, use a @kbd{C-u C-u} prefix.@*
  3042. If the cursor is on a headline, but not on a link, offer all links in the
  3043. headline and entry text. If you want to setup the frame configuration for
  3044. following links, customize @code{org-link-frame-setup}.

  3071. images that have no description part in the link, i.e.@: images that will also
  3072. be inlined during export. When called with a prefix argument, also display
  3073. images that do have a link description. You can ask for inline images to be
  3074. displayed at startup by configuring the variable

  3104. You can insert and follow links that have Org syntax not only in
  3105. Org, but in any Emacs buffer. For this, you should create two
  3106. global commands, like this (please select suitable global keys
  3107. yourself):
  3108. @lisp
  3109. (global-set-key "\C-c L" 'org-insert-link-global)

  3115. @cindex abbreviation, links
  3116. Long URLs can be cumbersome to type, and often many similar links are
  3117. needed in a document. For this you can use link abbreviations. An
  3118. abbreviated link looks like this
  3119. @example
  3120. [[linkword:tag][description]]
  3121. @end example
  3122. @noindent
  3123. @vindex org-link-abbrev-alist
  3124. where the tag is optional.
  3125. The @i{linkword} must be a word, starting with a letter, followed by
  3126. letters, numbers, @samp{-}, and @samp{_}. Abbreviations are resolved
  3127. according to the information in the variable @code{org-link-abbrev-alist}
  3128. that relates the linkwords to replacement text. Here is an example:
  3129. @smalllisp
  3130. @group
  3131. (setq org-link-abbrev-alist
  3132. '(("bugzilla" . "http://10.1.2.9/bugzilla/show_bug.cgi?id=")
  3133. ("url-to-ja" . "http://translate.google.fr/translate?sl=en&tl=ja&u=%h")
  3134. ("google" . "http://www.google.com/search?q=")
  3135. ("gmap" . "http://maps.google.com/maps?q=%s")
  3136. ("omap" . "http://nominatim.openstreetmap.org/search?q=%s&polygon=1")
  3137. ("ads" . "http://adsabs.harvard.edu/cgi-bin/nph-abs_connect?author=%s&db_key=AST")))
  3138. @end group
  3139. @end smalllisp
  3140. If the replacement text contains the string @samp{%s}, it will be
  3141. replaced with the tag. Using @samp{%h} instead of @samp{%s} will
  3142. url-encode the tag (see the example above, where we need to encode
  3143. the URL parameter.) Using @samp{%(my-function)} will pass the tag
  3144. to a custom function, and replace it by the resulting string.
  3145. If the replacement text don't contain any specifier, it will simply
  3146. be appended to the string in order to create the link.
  3147. Instead of a string, you may also specify a function that will be
  3148. called with the tag as the only argument to create the link.
  3149. With the above setting, you could link to a specific bug with
  3150. @code{[[bugzilla:129]]}, search the web for @samp{OrgMode} with
  3151. @code{[[google:OrgMode]]}, show the map location of the Free Software
  3152. Foundation @code{[[gmap:51 Franklin Street, Boston]]} or of Carsten office
  3153. @code{[[omap:Science Park 904, Amsterdam, The Netherlands]]} and find out
  3154. what the Org author is doing besides Emacs hacking with
  3155. @code{[[ads:Dominik,C]]}.
  3156. If you need special abbreviations just for a single Org buffer, you
  3157. can define them in the file with
  3158. @cindex #+LINK
  3159. @example
  3160. #+LINK: bugzilla http://10.1.2.9/bugzilla/show_bug.cgi?id=
  3161. #+LINK: google http://www.google.com/search?q=%s
  3162. @end example
  3163. @noindent
  3164. In-buffer completion (@pxref{Completion}) can be used after @samp{[} to
  3165. complete link abbreviations. You may also define a function
  3166. @code{org-PREFIX-complete-link} that implements special (e.g.@: completion)
  3167. support for inserting such a link with @kbd{C-c C-l}. Such a function should
  3168. not accept any arguments, and return the full link with prefix.

  3173. File links can contain additional information to make Emacs jump to a
  3174. particular location in the file when following a link. This can be a
  3175. line number or a search option after a double@footnote{For backward
  3176. compatibility, line numbers can also follow a single colon.} colon. For
  3177. example, when the command @kbd{C-c l} creates a link (@pxref{Handling
  3178. links}) to a file, it encodes the words in the current line as a search
  3179. string that can be used to find this line back later when following the
  3180. link with @kbd{C-c C-o}.
  3181. Here is the syntax of the different ways to attach a search to a file
  3182. link, together with an explanation:
  3183. @example
  3184. [[file:~/code/main.c::255]]
  3185. [[file:~/xx.org::My Target]]
  3186. [[file:~/xx.org::*My Target]]
  3187. [[file:~/xx.org::#my-custom-id]]
  3188. [[file:~/xx.org::/regexp/]]
  3189. @end example
  3190. @table @code
  3191. @item 255
  3192. Jump to line 255.
  3193. @item My Target
  3194. Search for a link target @samp{<<My Target>>}, or do a text search for
  3195. @samp{my target}, similar to the search in internal links, see
  3196. @ref{Internal links}. In HTML export (@pxref{HTML export}), such a file
  3197. link will become a HTML reference to the corresponding named anchor in
  3198. the linked file.
  3199. @item *My Target
  3200. In an Org file, restrict search to headlines.
  3201. @item #my-custom-id
  3202. Link to a heading with a @code{CUSTOM_ID} property
  3203. @item /regexp/
  3204. Do a regular expression search for @code{regexp}. This uses the Emacs
  3205. command @code{occur} to list all matches in a separate window. If the
  3206. target file is in Org mode, @code{org-occur} is used to create a
  3207. sparse tree with the matches.
  3208. @c If the target file is a directory,
  3209. @c @code{grep} will be used to search all files in the directory.
  3210. @end table
  3211. As a degenerate case, a file link with an empty file name can be used
  3212. to search the current file. For example, @code{[[file:::find me]]} does
  3213. a search for @samp{find me} in the current file, just as
  3214. @samp{[[find me]]} would.

  3219. The default mechanism for creating search strings and for doing the
  3220. actual search related to a file link may not work correctly in all
  3221. cases. For example, Bib@TeX{} database files have many entries like
  3222. @samp{year="1993"} which would not result in good search strings,
  3223. because the only unique identification for a Bib@TeX{} entry is the
  3224. citation key.
  3225. @vindex org-create-file-search-functions
  3226. @vindex org-execute-file-search-functions
  3227. If you come across such a problem, you can write custom functions to set
  3228. the right search string for a particular file type, and to do the search
  3229. for the string in the file. Using @code{add-hook}, these functions need
  3230. to be added to the hook variables
  3231. @code{org-create-file-search-functions} and
  3232. @code{org-execute-file-search-functions}. See the docstring for these
  3233. variables for more information. Org actually uses this mechanism
  3234. for Bib@TeX{} database files, and you can use the corresponding code as
  3235. an implementation example. See the file @file{org-bibtex.el}.

  3239. Org mode does not maintain TODO lists as separate documents@footnote{Of
  3240. course, you can make a document that contains only long lists of TODO items,
  3241. but this is not required.}. Instead, TODO items are an integral part of the
  3242. notes file, because TODO items usually come up while taking notes! With Org
  3243. mode, simply mark any entry in a tree as being a TODO item. In this way,
  3244. information is not duplicated, and the entire context from which the TODO
  3245. item emerged is always present.
  3246. Of course, this technique for managing TODO items scatters them
  3247. throughout your notes file. Org mode compensates for this by providing
  3248. methods to give you an overview of all the things that you have to do.

  3339. You can use TODO keywords to indicate different @emph{sequential} states
  3340. in the process of working on an item, for example@footnote{Changing
  3341. this variable only becomes effective after restarting Org mode in a
  3342. buffer.}:
  3343. @lisp
  3344. (setq org-todo-keywords
  3345. '((sequence "TODO" "FEEDBACK" "VERIFY" "|" "DONE" "DELEGATED")))
  3346. @end lisp
  3347. The vertical bar separates the TODO keywords (states that @emph{need
  3348. action}) from the DONE states (which need @emph{no further action}). If
  3349. you don't provide the separator bar, the last state is used as the DONE
  3350. state.
  3351. @cindex completion, of TODO keywords
  3352. With this setup, the command @kbd{C-c C-t} will cycle an entry from TODO
  3353. to FEEDBACK, then to VERIFY, and finally to DONE and DELEGATED. You may
  3354. also use a numeric prefix argument to quickly select a specific state. For
  3355. example @kbd{C-3 C-c C-t} will change the state immediately to VERIFY.
  3356. Or you can use @kbd{S-@key{left}} to go backward through the sequence. If you
  3357. define many keywords, you can use in-buffer completion
  3358. (@pxref{Completion}) or even a special one-key selection scheme
  3359. (@pxref{Fast access to TODO states}) to insert these words into the
  3360. buffer. Changing a TODO state can be logged with a timestamp, see
  3361. @ref{Tracking TODO state changes}, for more information.
  3362. @node TODO types, Multiple sets in one file, Workflow states, TODO extensions
  3363. @subsection TODO keywords as types
  3364. @cindex TODO types
  3365. @cindex names as TODO keywords
  3366. @cindex types as TODO keywords
  3367. The second possibility is to use TODO keywords to indicate different
  3368. @emph{types} of action items. For example, you might want to indicate
  3369. that items are for ``work'' or ``home''. Or, when you work with several
  3370. people on a single project, you might want to assign action items
  3371. directly to persons, by using their names as TODO keywords. This would
  3372. be set up like this:
  3373. @lisp
  3374. (setq org-todo-keywords '((type "Fred" "Sara" "Lucy" "|" "DONE")))
  3375. @end lisp
  3376. In this case, different keywords do not indicate a sequence, but rather
  3377. different types. So the normal work flow would be to assign a task to a
  3378. person, and later to mark it DONE. Org mode supports this style by adapting
  3379. the workings of the command @kbd{C-c C-t}@footnote{This is also true for the
  3380. @kbd{t} command in the timeline and agenda buffers.}. When used several
  3381. times in succession, it will still cycle through all names, in order to first
  3382. select the right type for a task. But when you return to the item after some
  3383. time and execute @kbd{C-c C-t} again, it will switch from any name directly
  3384. to DONE. Use prefix arguments or completion to quickly select a specific
  3385. name. You can also review the items of a specific TODO type in a sparse tree
  3386. by using a numeric prefix to @kbd{C-c / t}. For example, to see all things
  3387. Lucy has to do, you would use @kbd{C-3 C-c / t}. To collect Lucy's items
  3388. from all agenda files into a single buffer, you would use the numeric prefix
  3389. argument as well when creating the global TODO list: @kbd{C-3 C-c a t}.

  3391. @subsection Multiple keyword sets in one file
  3392. @cindex TODO keyword sets
  3393. Sometimes you may want to use different sets of TODO keywords in
  3394. parallel. For example, you may want to have the basic
  3395. @code{TODO}/@code{DONE}, but also a workflow for bug fixing, and a
  3396. separate state indicating that an item has been canceled (so it is not
  3397. DONE, but also does not require action). Your setup would then look
  3398. like this:
  3399. @lisp
  3400. (setq org-todo-keywords
  3401. '((sequence "TODO" "|" "DONE")
  3402. (sequence "REPORT" "BUG" "KNOWNCAUSE" "|" "FIXED")
  3403. (sequence "|" "CANCELED")))
  3404. @end lisp
  3405. The keywords should all be different, this helps Org mode to keep track
  3406. of which subsequence should be used for a given entry. In this setup,
  3407. @kbd{C-c C-t} only operates within a subsequence, so it switches from
  3408. @code{DONE} to (nothing) to @code{TODO}, and from @code{FIXED} to
  3409. (nothing) to @code{REPORT}. Therefore you need a mechanism to initially
  3410. select the correct sequence. Besides the obvious ways like typing a
  3411. keyword or using completion, you may also apply the following commands:
  3412. @table @kbd
  3413. @kindex C-S-@key{right}
  3414. @kindex C-S-@key{left}
  3415. @kindex C-u C-u C-c C-t
  3416. @item C-u C-u C-c C-t
  3417. @itemx C-S-@key{right}
  3418. @itemx C-S-@key{left}
  3419. These keys jump from one TODO subset to the next. In the above example,
  3420. @kbd{C-u C-u C-c C-t} or @kbd{C-S-@key{right}} would jump from @code{TODO} or
  3421. @code{DONE} to @code{REPORT}, and any of the words in the second row to
  3422. @code{CANCELED}. Note that the @kbd{C-S-} key binding conflict with
  3423. @code{shift-selection-mode} (@pxref{Conflicts}).
  3424. @kindex S-@key{right}
  3425. @kindex S-@key{left}
  3426. @item S-@key{right}
  3427. @itemx S-@key{left}
  3428. @kbd{S-@key{<left>}} and @kbd{S-@key{<right>}} and walk through @emph{all}
  3429. keywords from all sets, so for example @kbd{S-@key{<right>}} would switch
  3430. from @code{DONE} to @code{REPORT} in the example above. See also
  3431. @ref{Conflicts}, for a discussion of the interaction with
  3432. @code{shift-selection-mode}.

  3436. If you would like to quickly change an entry to an arbitrary TODO state
  3437. instead of cycling through the states, you can set up keys for single-letter
  3438. access to the states. This is done by adding the selection character after
  3439. each keyword, in parentheses@footnote{All characters are allowed except
  3440. @code{@@^!}, which have a special meaning here.}. For example:
  3441. @lisp

  3448. If you then press @kbd{C-c C-t} followed by the selection key, the entry
  3449. will be switched to this state. @kbd{SPC} can be used to remove any TODO
  3450. keyword from an entry.@footnote{Check also the variable
  3451. @code{org-fast-tag-selection-include-todo}, it allows you to change the TODO
  3452. state through the tags interface (@pxref{Setting tags}), in case you like to
  3453. mingle the two concepts. Note that this means you need to come up with
  3454. unique keys across both sets of keywords.}

  3462. It can be very useful to use different aspects of the TODO mechanism in
  3463. different files. For file-local settings, you need to add special lines
  3464. to the file which set the keywords and interpretation for that file
  3465. only. For example, to set one of the two examples discussed above, you
  3466. need one of the following lines, starting in column zero anywhere in the
  3467. file:
  3468. @example
  3469. #+TODO: TODO FEEDBACK VERIFY | DONE CANCELED
  3470. @end example
  3471. @noindent (you may also write @code{#+SEQ_TODO} to be explicit about the
  3472. interpretation, but it means the same as @code{#+TODO}), or
  3473. @example
  3474. #+TYP_TODO: Fred Sara Lucy Mike | DONE
  3475. @end example
  3476. A setup for using several sets in parallel would be:
  3477. @example
  3478. #+TODO: TODO | DONE
  3479. #+TODO: REPORT BUG KNOWNCAUSE | FIXED
  3480. #+TODO: | CANCELED
  3481. @end example
  3482. @cindex completion, of option keywords
  3483. @kindex M-@key{TAB}
  3484. @noindent To make sure you are using the correct keyword, type
  3485. @samp{#+} into the buffer and then use @kbd{M-@key{TAB}} completion.
  3486. @cindex DONE, final TODO keyword
  3487. Remember that the keywords after the vertical bar (or the last keyword
  3488. if no bar is there) must always mean that the item is DONE (although you
  3489. may use a different word). After changing one of these lines, use
  3490. @kbd{C-c C-c} with the cursor still in the line to make the changes
  3491. known to Org mode@footnote{Org mode parses these lines only when
  3492. Org mode is activated after visiting a file. @kbd{C-c C-c} with the

  3501. Org mode highlights TODO keywords with special faces: @code{org-todo}
  3502. for keywords indicating that an item still has to be acted upon, and
  3503. @code{org-done} for keywords indicating that an item is finished. If
  3504. you are using more than 2 different states, you might want to use
  3505. special faces for some of them. This can be done using the variable
  3506. @code{org-todo-keyword-faces}. For example:
  3507. @lisp
  3508. @group
  3509. (setq org-todo-keyword-faces
  3510. '(("TODO" . org-warning) ("STARTED" . "yellow")
  3511. ("CANCELED" . (:foreground "blue" :weight bold))))
  3512. @end group
  3513. @end lisp
  3514. While using a list with face properties as shown for CANCELED @emph{should}
  3515. work, this does not always seem to be the case. If necessary, define a
  3516. special face and use that. A string is interpreted as a color. The variable

  3525. The structure of Org files (hierarchy and lists) makes it easy to define TODO
  3526. dependencies. Usually, a parent TODO task should not be marked DONE until
  3527. all subtasks (defined as children tasks) are marked as DONE. And sometimes
  3528. there is a logical sequence to a number of (sub)tasks, so that one task
  3529. cannot be acted upon before all siblings above it are done. If you customize
  3530. the variable @code{org-enforce-todo-dependencies}, Org will block entries
  3531. from changing state to DONE while they have children that are not DONE.
  3532. Furthermore, if an entry has a property @code{ORDERED}, each of its children
  3533. will be blocked until all earlier siblings are marked DONE. Here is an
  3534. example:
  3535. @example
  3536. * TODO Blocked until (two) is done
  3537. ** DONE one
  3538. ** TODO two

  3550. @cindex property, ORDERED
  3551. Toggle the @code{ORDERED} property of the current entry. A property is used
  3552. for this behavior because this should be local to the current entry, not
  3553. inherited like a tag. However, if you would like to @i{track} the value of
  3554. this property with a tag for better visibility, customize the variable
  3555. @code{org-track-ordered-property-with-tag}.

  3560. If you set the variable @code{org-agenda-dim-blocked-tasks}, TODO entries

  3593. @lisp
  3594. (setq org-log-done 'time)
  3595. @end lisp
  3596. @noindent
  3597. Then each time you turn an entry from a TODO (not-done) state into any
  3598. of the DONE states, a line @samp{CLOSED: [timestamp]} will be inserted
  3599. just after the headline. If you turn the entry back into a TODO item
  3600. through further state cycling, that line will be removed again. If you
  3601. want to record a note along with the timestamp, use@footnote{The
  3602. corresponding in-buffer setting is: @code{#+STARTUP: lognotedone}}
  3603. @lisp
  3604. (setq org-log-done 'note)

  3607. You will then be prompted for a note, and that note will be stored below

  3609. In the timeline (@pxref{Timeline}) and in the agenda
  3610. (@pxref{Weekly/daily agenda}), you can then use the @kbd{l} key to

  3619. When TODO keywords are used as workflow states (@pxref{Workflow states}), you
  3620. might want to keep track of when a state change occurred and maybe take a
  3621. note about this change. You can either record just a timestamp, or a
  3622. time-stamped note for a change. These records will be inserted after the
  3623. headline as an itemized list, newest first@footnote{See the variable
  3624. @code{org-log-states-order-reversed}}. When taking a lot of notes, you might
  3625. want to get the notes out of the way into a drawer (@pxref{Drawers}).
  3626. Customize the variable @code{org-log-into-drawer} to get this behavior---the
  3627. recommended drawer for this is called @code{LOGBOOK}@footnote{Note that the
  3628. @code{LOGBOOK} drawer is unfolded when pressing @key{SPC} in the agenda to
  3629. show an entry---use @key{C-u SPC} to keep it folded here}. You can also
  3630. overrule the setting of this variable for a subtree by setting a
  3631. @code{LOG_INTO_DRAWER} property.
  3632. Since it is normally too much to record a note for every state, Org mode
  3633. expects configuration on a per-keyword basis for this. This is achieved by
  3634. adding special markers @samp{!} (for a timestamp) or @samp{@@} (for a note
  3635. with timestamp) in parentheses after each keyword. For example, with the
  3636. setting
  3637. @lisp
  3638. (setq org-todo-keywords
  3639. '((sequence "TODO(t)" "WAIT(w@@/!)" "|" "DONE(d!)" "CANCELED(c@@)")))
  3640. @end lisp
  3641. To record a timestamp without a note for TODO keywords configured with
  3642. @samp{@@}, just type @kbd{C-c C-c} to enter a blank note when prompted.
  3643. @noindent
  3644. @vindex org-log-done
  3645. you not only define global TODO keywords and fast access keys, but also
  3646. request that a time is recorded when the entry is set to
  3647. DONE@footnote{It is possible that Org mode will record two timestamps
  3648. when you are using both @code{org-log-done} and state change logging.
  3649. However, it will never prompt for two notes---if you have configured
  3650. both, the state change recording note will take precedence and cancel
  3651. the @samp{Closing Note}.}, and that a note is recorded when switching to
  3652. WAIT or CANCELED. The setting for WAIT is even more special: the
  3653. @samp{!} after the slash means that in addition to the note taken when
  3654. entering the state, a timestamp should be recorded when @i{leaving} the
  3655. WAIT state, if and only if the @i{target} state does not configure
  3656. logging for entering it. So it has no effect when switching from WAIT
  3657. to DONE, because DONE is configured to record a timestamp only. But
  3658. when switching from WAIT back to TODO, the @samp{/!} in the WAIT
  3659. setting now triggers a timestamp even though TODO has no logging
  3660. configured.
  3661. You can use the exact same syntax for setting logging preferences local
  3662. to a buffer:
  3663. @example
  3664. #+TODO: TODO(t) WAIT(w@@/!) | DONE(d!) CANCELED(c@@)
  3665. @end example
  3666. @cindex property, LOGGING
  3667. In order to define logging settings that are local to a subtree or a
  3668. single item, define a LOGGING property in this entry. Any non-empty
  3669. LOGGING property resets all logging settings to nil. You may then turn
  3670. on logging for this specific tree using STARTUP keywords like
  3671. @code{lognotedone} or @code{logrepeat}, as well as adding state specific
  3672. settings like @code{TODO(!)}. For example
  3673. @example

  3689. @cindex habits
  3690. Org has the ability to track the consistency of a special category of TODOs,
  3691. called ``habits''. A habit has the following properties:
  3692. @enumerate
  3693. @item
  3694. You have enabled the @code{habits} module by customizing the variable
  3695. @code{org-modules}.
  3696. @item
  3697. The habit is a TODO item, with a TODO keyword representing an open state.
  3698. @item
  3699. The property @code{STYLE} is set to the value @code{habit}.
  3700. @item
  3701. The TODO has a scheduled date, usually with a @code{.+} style repeat
  3702. interval. A @code{++} style may be appropriate for habits with time
  3703. constraints, e.g., must be done on weekends, or a @code{+} style for an
  3704. unusual habit that can have a backlog, e.g., weekly reports.
  3705. @item
  3706. The TODO may also have minimum and maximum ranges specified by using the
  3707. syntax @samp{.+2d/3d}, which says that you want to do the task at least every
  3708. three days, but at most every two days.
  3709. @item
  3710. You must also have state logging for the @code{DONE} state enabled
  3711. (@pxref{Tracking TODO state changes}), in order for historical data to be
  3712. represented in the consistency graph. If it is not enabled it is not an
  3713. error, but the consistency graphs will be largely meaningless.
  3714. @end enumerate
  3715. To give you an idea of what the above rules look like in action, here's an
  3716. actual habit with some history:
  3717. @example

  3733. :END:
  3734. @end example
  3735. What this habit says is: I want to shave at most every 2 days (given by the
  3736. @code{SCHEDULED} date and repeat interval) and at least every 4 days. If
  3737. today is the 15th, then the habit first appears in the agenda on Oct 17,
  3738. after the minimum of 2 days has elapsed, and will appear overdue on Oct 19,
  3739. after four days have elapsed.
  3740. What's really useful about habits is that they are displayed along with a
  3741. consistency graph, to show how consistent you've been at getting that task
  3742. done in the past. This graph shows every day that the task was done over the
  3743. past three weeks, with colors for each day. The colors used are:
  3744. @table @code
  3745. @item Blue
  3746. If the task wasn't to be done yet on that day.
  3747. @item Green
  3748. If the task could have been done on that day.
  3749. @item Yellow
  3750. If the task was going to be overdue the next day.
  3751. @item Red
  3752. If the task was overdue on that day.
  3753. @end table
  3754. In addition to coloring each day, the day is also marked with an asterisk if
  3755. the task was actually done that day, and an exclamation mark to show where
  3756. the current day falls in the graph.
  3757. There are several configuration variables that can be used to change the way
  3758. habits are displayed in the agenda.
  3759. @table @code
  3760. @item org-habit-graph-column
  3761. The buffer column at which the consistency graph should be drawn. This will
  3762. overwrite any text in that column, so it is a good idea to keep your habits'
  3763. titles brief and to the point.
  3764. @item org-habit-preceding-days
  3765. The amount of history, in days before today, to appear in consistency graphs.
  3766. @item org-habit-following-days
  3767. The number of days after today that will appear in consistency graphs.
  3768. @item org-habit-show-habits-only-for-today

  3770. default.
  3771. @end table
  3772. Lastly, pressing @kbd{K} in the agenda buffer will cause habits to
  3773. temporarily be disabled and they won't appear at all. Press @kbd{K} again to
  3774. bring them back. They are also subject to tag filtering, if you have habits
  3775. which should only be done in certain contexts, for example.

  3777. @section Priorities
  3778. @cindex priorities
  3779. If you use Org mode extensively, you may end up with enough TODO items that
  3780. it starts to make sense to prioritize them. Prioritizing can be done by
  3781. placing a @emph{priority cookie} into the headline of a TODO item, like this
  3782. @example
  3783. *** TODO [#A] Write letter to Sam Fortune
  3784. @end example
  3785. @noindent
  3786. @vindex org-priority-faces
  3787. By default, Org mode supports three priorities: @samp{A}, @samp{B}, and
  3788. @samp{C}. @samp{A} is the highest priority. An entry without a cookie is
  3789. treated just like priority @samp{B}. Priorities make a difference only for
  3790. sorting in the agenda (@pxref{Weekly/daily agenda}); outside the agenda, they
  3791. have no inherent meaning to Org mode. The cookies can be highlighted with
  3792. special faces by customizing the variable @code{org-priority-faces}.
  3793. Priorities can be attached to any outline node; they do not need to be TODO
  3794. items.
  3795. @table @kbd
  3796. @item @kbd{C-c ,}
  3797. @kindex @kbd{C-c ,}
  3798. @findex org-priority
  3799. Set the priority of the current headline (@command{org-priority}). The
  3800. command prompts for a priority character @samp{A}, @samp{B} or @samp{C}.
  3801. When you press @key{SPC} instead, the priority cookie is removed from the
  3802. headline. The priorities can also be changed ``remotely'' from the timeline
  3803. and agenda buffer with the @kbd{,} command (@pxref{Agenda commands}).
  3804. @c
  3805. @orgcmdkkcc{S-@key{up},S-@key{down},org-priority-up,org-priority-down}

  3807. Increase/decrease priority of current headline@footnote{See also the option
  3808. @code{org-priority-start-cycle-with-default}.}. Note that these keys are
  3809. also used to modify timestamps (@pxref{Creating timestamps}). See also
  3810. @ref{Conflicts}, for a discussion of the interaction with
  3811. @code{shift-selection-mode}.
  3812. @end table
  3813. @vindex org-highest-priority
  3814. @vindex org-lowest-priority
  3815. @vindex org-default-priority
  3816. You can change the range of allowed priorities by setting the variables
  3817. @code{org-highest-priority}, @code{org-lowest-priority}, and
  3818. @code{org-default-priority}. For an individual buffer, you may set
  3819. these values (highest, lowest, default) like this (please make sure that
  3820. the highest priority is earlier in the alphabet than the lowest
  3821. priority):
  3822. @cindex #+PRIORITIES

  3830. @vindex org-agenda-todo-list-sublevels
  3831. It is often advisable to break down large tasks into smaller, manageable
  3832. subtasks. You can do this by creating an outline tree below a TODO item,
  3833. with detailed subtasks on the tree@footnote{To keep subtasks out of the
  3834. global TODO list, see the @code{org-agenda-todo-list-sublevels}.}. To keep
  3835. the overview over the fraction of subtasks that are already completed, insert
  3836. either @samp{[/]} or @samp{[%]} anywhere in the headline. These cookies will
  3837. be updated each time the TODO status of a child changes, or when pressing
  3838. @kbd{C-c C-c} on the cookie. For example:
  3839. @example
  3840. * Organize Party [33%]
  3841. ** TODO Call people [1/2]
  3842. *** TODO Peter
  3843. *** DONE Sarah
  3844. ** TODO Buy food
  3845. ** DONE Talk to neighbor
  3846. @end example
  3847. @cindex property, COOKIE_DATA
  3848. If a heading has both checkboxes and TODO children below it, the meaning of
  3849. the statistics cookie become ambiguous. Set the property
  3850. @code{COOKIE_DATA} to either @samp{checkbox} or @samp{todo} to resolve
  3851. this issue.
  3852. @vindex org-hierarchical-todo-statistics
  3853. If you would like to have the statistics cookie count any TODO entries in the
  3854. subtree (not just direct children), configure the variable
  3855. @code{org-hierarchical-todo-statistics}. To do this for a single subtree,
  3856. include the word @samp{recursive} into the value of the @code{COOKIE_DATA}
  3857. property.
  3858. @example
  3859. * Parent capturing statistics [2/20]
  3860. :PROPERTIES:
  3861. :COOKIE_DATA: todo recursive
  3862. :END:
  3863. @end example
  3864. If you would like a TODO entry to automatically change to DONE
  3865. when all children are done, you can use the following setup:
  3866. @example
  3867. (defun org-summary-todo (n-done n-not-done)
  3868. "Switch entry to DONE when all subentries are done, to TODO otherwise."
  3869. (let (org-log-done org-log-states) ; turn off logging
  3870. (org-todo (if (= n-not-done 0) "DONE" "TODO"))))
  3871. (add-hook 'org-after-todo-statistics-hook 'org-summary-todo)
  3872. @end example
  3873. Another possibility is the use of checkboxes to identify (a hierarchy of) a
  3874. large number of subtasks (@pxref{Checkboxes}).
  3875. @node Checkboxes, , Breaking down tasks, TODO Items
  3876. @section Checkboxes
  3877. @cindex checkboxes
  3878. @vindex org-list-automatic-rules
  3879. Every item in a plain list@footnote{With the exception of description
  3880. lists. But you can allow it by modifying @code{org-list-automatic-rules}
  3881. accordingly.} (@pxref{Plain lists}) can be made into a checkbox by starting
  3882. it with the string @samp{[ ]}. This feature is similar to TODO items
  3883. (@pxref{TODO Items}), but is more lightweight. Checkboxes are not included
  3884. into the global TODO list, so they are often great to split a task into a
  3885. number of simple steps. Or you can use them in a shopping list. To toggle a
  3886. checkbox, use @kbd{C-c C-c}, or use the mouse (thanks to Piotr Zielinski's
  3887. @file{org-mouse.el}).
  3888. Here is an example of a checkbox list.
  3889. @example
  3890. * TODO Organize party [2/4]
  3891. - [-] call people [1/3]
  3892. - [ ] Peter
  3893. - [X] Sarah
  3894. - [ ] Sam
  3895. - [X] order food
  3896. - [ ] think about what music to play
  3897. - [X] talk to the neighbors
  3898. @end example
  3899. Checkboxes work hierarchically, so if a checkbox item has children that
  3900. are checkboxes, toggling one of the children checkboxes will make the
  3901. parent checkbox reflect if none, some, or all of the children are
  3902. checked.
  3903. @cindex statistics, for checkboxes
  3904. @cindex checkbox statistics
  3905. @cindex property, COOKIE_DATA
  3906. @vindex org-hierarchical-checkbox-statistics
  3907. The @samp{[2/4]} and @samp{[1/3]} in the first and second line are cookies
  3908. indicating how many checkboxes present in this entry have been checked off,
  3909. and the total number of checkboxes present. This can give you an idea on how
  3910. many checkboxes remain, even without opening a folded entry. The cookies can
  3911. be placed into a headline or into (the first line of) a plain list item.
  3912. Each cookie covers checkboxes of direct children structurally below the
  3913. headline/item on which the cookie appears@footnote{Set the variable
  3914. @code{org-hierarchical-checkbox-statistics} if you want such cookies to
  3915. count all checkboxes below the cookie, not just those belonging to direct
  3916. children.}. You have to insert the cookie yourself by typing either
  3917. @samp{[/]} or @samp{[%]}. With @samp{[/]} you get an @samp{n out of m}
  3918. result, as in the examples above. With @samp{[%]} you get information about
  3919. the percentage of checkboxes checked (in the above example, this would be
  3920. @samp{[50%]} and @samp{[33%]}, respectively). In a headline, a cookie can
  3921. count either checkboxes below the heading or TODO states of children, and it
  3922. will display whatever was changed last. Set the property @code{COOKIE_DATA}
  3923. to either @samp{checkbox} or @samp{todo} to resolve this issue.
  3924. @cindex blocking, of checkboxes
  3925. @cindex checkbox blocking
  3926. @cindex property, ORDERED
  3927. If the current outline node has an @code{ORDERED} property, checkboxes must
  3928. be checked off in sequence, and an error will be thrown if you try to check
  3929. off a box while there are unchecked boxes above it.
  3930. @noindent The following commands work with checkboxes:
  3931. @table @kbd
  3932. @orgcmd{C-c C-c,org-toggle-checkbox}
  3933. Toggle checkbox status or (with prefix arg) checkbox presence at point.
  3934. With a single prefix argument, add an empty checkbox or remove the current
  3935. one@footnote{`C-u C-c C-c' on the @emph{first} item of a list with no checkbox
  3936. will add checkboxes to the rest of the list.}. With a double prefix argument, set it to @samp{[-]}, which is
  3937. considered to be an intermediate state.
  3938. @orgcmd{C-c C-x C-b,org-toggle-checkbox}
  3939. Toggle checkbox status or (with prefix arg) checkbox presence at point. With
  3940. double prefix argument, set it to @samp{[-]}, which is considered to be an
  3941. intermediate state.
  3942. @itemize @minus
  3943. @item
  3944. If there is an active region, toggle the first checkbox in the region
  3945. and set all remaining boxes to the same status as the first. With a prefix
  3946. arg, add or remove the checkbox for all items in the region.
  3947. @item
  3948. If the cursor is in a headline, toggle checkboxes in the region between
  3949. this headline and the next (so @emph{not} the entire subtree).
  3950. @item
  3951. If there is no active region, just toggle the checkbox at point.
  3952. @end itemize
  3953. @orgcmd{M-S-@key{RET},org-insert-todo-heading}
  3954. Insert a new item with a checkbox. This works only if the cursor is already
  3955. in a plain list item (@pxref{Plain lists}).
  3956. @orgcmd{C-c C-x o,org-toggle-ordered-property}
  3957. @vindex org-track-ordered-property-with-tag
  3958. @cindex property, ORDERED
  3959. Toggle the @code{ORDERED} property of the entry, to toggle if checkboxes must
  3960. be checked off in sequence. A property is used for this behavior because
  3961. this should be local to the current entry, not inherited like a tag.
  3962. However, if you would like to @i{track} the value of this property with a tag
  3963. for better visibility, customize the variable
  3964. @code{org-track-ordered-property-with-tag}.
  3965. @orgcmd{C-c #,org-update-statistics-cookies}
  3966. Update the statistics cookie in the current outline entry. When called with
  3967. a @kbd{C-u} prefix, update the entire file. Checkbox statistic cookies are
  3968. updated automatically if you toggle checkboxes with @kbd{C-c C-c} and make
  3969. new ones with @kbd{M-S-@key{RET}}. TODO statistics cookies update when
  3970. changing TODO states. If you delete boxes/entries or add/change them by
  3971. hand, use this command to get things back into sync.

  3985. @samp{@@}. Tags must be preceded and followed by a single colon, e.g.,
  3986. @samp{:work:}. Several tags can be specified, as in @samp{:work:urgent:}.
  3987. Tags will by default be in bold face with the same color as the headline.
  3988. You may specify special faces for specific tags using the variable
  3989. @code{org-tag-faces}, in much the same way as you can for TODO keywords

  4012. explicitly marked with those tags. You can also set tags that all entries in
  4013. a file should inherit just as if these tags were defined in a hypothetical
  4014. level zero that surrounds the entire file. Use a line like this@footnote{As
  4015. with all these in-buffer settings, pressing @kbd{C-c C-c} activates any
  4016. changes in the line.}:
  4017. @cindex #+FILETAGS

  4027. @vindex org-tags-match-list-sublevels
  4028. When a headline matches during a tags search while tag inheritance is turned

  4030. as well@footnote{This is only true if the search does not involve more
  4031. complex tests including properties (@pxref{Property searches}).}. The list
  4032. of matches may then become very long. If you only want to see the first tags

  4045. @cindex completion, of tags

  4047. Enter new tags for the current headline. Org mode will either offer
  4048. completion or a special single-key interface for setting tags, see
  4049. below. After pressing @key{RET}, the tags will be inserted and aligned
  4050. to @code{org-tags-column}. When called with a @kbd{C-u} prefix, all
  4051. tags in the current buffer will be aligned to that column, just to make
  4052. things look nice. TAGS are automatically realigned after promotion,
  4053. demotion, and TODO state changes (@pxref{TODO basics}).
  4054. @orgcmd{C-c C-c,org-set-tags-command}
  4055. When the cursor is in a headline, this does the same as @kbd{C-c C-q}.
  4056. @end table
  4057. @vindex org-tag-alist
  4058. Org supports tag insertion based on a @emph{list of tags}. By
  4059. default this list is constructed dynamically, containing all tags
  4060. currently used in the buffer. You may also globally specify a hard list
  4061. of tags with the variable @code{org-tag-alist}. Finally you can set
  4062. the default tags for a given file with lines like
  4063. @cindex #+TAGS
  4064. @example
  4065. #+TAGS: @@work @@home @@tennisclub
  4066. #+TAGS: laptop car pc sailboat
  4067. @end example
  4068. If you have globally defined your preferred set of tags using the
  4069. variable @code{org-tag-alist}, but would like to use a dynamic tag list
  4070. in a specific file, add an empty TAGS option line to that file:
  4071. @example
  4072. #+TAGS:
  4073. @end example
  4074. @vindex org-tag-persistent-alist
  4075. If you have a preferred set of tags that you would like to use in every file,
  4076. in addition to those defined on a per-file basis by TAGS option lines, then
  4077. you may specify a list of tags with the variable
  4078. @code{org-tag-persistent-alist}. You may turn this off on a per-file basis
  4079. by adding a STARTUP option line to that file:
  4080. @example
  4081. #+STARTUP: noptag
  4082. @end example
  4083. By default Org mode uses the standard minibuffer completion facilities for
  4084. entering tags. However, it also implements another, quicker, tag selection
  4085. method called @emph{fast tag selection}. This allows you to select and
  4086. deselect tags with just a single key press. For this to work well you should
  4087. assign unique letters to most of your commonly used tags. You can do this
  4088. globally by configuring the variable @code{org-tag-alist} in your
  4089. @file{.emacs} file. For example, you may find the need to tag many items in
  4090. different files with @samp{:@@home:}. In this case you can set something
  4091. like:
  4092. @lisp
  4093. (setq org-tag-alist '(("@@work" . ?w) ("@@home" . ?h) ("laptop" . ?l)))
  4094. @end lisp
  4095. @noindent If the tag is only relevant to the file you are working on, then you
  4096. can instead set the TAGS option line as:
  4097. @example
  4098. #+TAGS: @@work(w) @@home(h) @@tennisclub(t) laptop(l) pc(p)
  4099. @end example
  4100. @noindent The tags interface will show the available tags in a splash
  4101. window. If you want to start a new line after a specific tag, insert
  4102. @samp{\n} into the tag list
  4103. @example
  4104. #+TAGS: @@work(w) @@home(h) @@tennisclub(t) \n laptop(l) pc(p)
  4105. @end example
  4106. @noindent or write them in two lines:
  4107. @example
  4108. #+TAGS: @@work(w) @@home(h) @@tennisclub(t)
  4109. #+TAGS: laptop(l) pc(p)
  4110. @end example
  4111. @noindent
  4112. You can also group together tags that are mutually exclusive by using
  4113. braces, as in:
  4114. @example
  4115. #+TAGS: @{ @@work(w) @@home(h) @@tennisclub(t) @} laptop(l) pc(p)
  4116. @end example
  4117. @noindent you indicate that at most one of @samp{@@work}, @samp{@@home},
  4118. and @samp{@@tennisclub} should be selected. Multiple such groups are allowed.
  4119. @noindent Don't forget to press @kbd{C-c C-c} with the cursor in one of
  4120. these lines to activate any changes.
  4121. @noindent
  4122. To set these mutually exclusive groups in the variable @code{org-tags-alist},
  4123. you must use the dummy tags @code{:startgroup} and @code{:endgroup} instead
  4124. of the braces. Similarly, you can use @code{:newline} to indicate a line
  4125. break. The previous example would be set globally by the following
  4126. configuration:
  4127. @lisp
  4128. (setq org-tag-alist '((:startgroup . nil)
  4129. ("@@work" . ?w) ("@@home" . ?h)
  4130. ("@@tennisclub" . ?t)
  4131. (:endgroup . nil)
  4132. ("laptop" . ?l) ("pc" . ?p)))
  4133. @end lisp
  4134. If at least one tag has a selection key then pressing @kbd{C-c C-c} will
  4135. automatically present you with a special interface, listing inherited tags,
  4136. the tags of the current headline, and a list of all valid tags with
  4137. corresponding keys@footnote{Keys will automatically be assigned to tags which
  4138. have no configured keys.}. In this interface, you can use the following
  4139. keys:
  4140. @table @kbd
  4141. @item a-z...
  4142. Pressing keys assigned to tags will add or remove them from the list of
  4143. tags in the current line. Selecting a tag in a group of mutually
  4144. exclusive tags will turn off any other tags from that group.
  4145. @kindex @key{TAB}
  4146. @item @key{TAB}
  4147. Enter a tag in the minibuffer, even if the tag is not in the predefined
  4148. list. You will be able to complete on all tags present in the buffer.
  4149. You can also add several tags: just separate them with a comma.
  4150. @kindex @key{SPC}
  4151. @item @key{SPC}
  4152. Clear all tags for this line.
  4153. @kindex @key{RET}
  4154. @item @key{RET}
  4155. Accept the modified set.
  4156. @item C-g
  4157. Abort without installing changes.
  4158. @item q
  4159. If @kbd{q} is not assigned to a tag, it aborts like @kbd{C-g}.
  4160. @item !
  4161. Turn off groups of mutually exclusive tags. Use this to (as an
  4162. exception) assign several tags from such a group.
  4163. @item C-c

  4169. This method lets you assign tags to a headline with very few keys. With
  4170. the above setup, you could clear the current tags and set @samp{@@home},
  4171. @samp{laptop} and @samp{pc} tags with just the following keys: @kbd{C-c
  4172. C-c @key{SPC} h l p @key{RET}}. Switching from @samp{@@home} to
  4173. @samp{@@work} would be done with @kbd{C-c C-c w @key{RET}} or
  4174. alternatively with @kbd{C-c C-c C-c w}. Adding the non-predefined tag
  4175. @samp{Sarah} could be done with @kbd{C-c C-c @key{TAB} S a r a h
  4176. @key{RET} @key{RET}}.
  4177. @vindex org-fast-tag-selection-single-key
  4178. If you find that most of the time you need only a single key press to
  4179. modify your list of tags, set the variable
  4180. @code{org-fast-tag-selection-single-key}. Then you no longer have to
  4181. press @key{RET} to exit fast tag selection---it will immediately exit
  4182. after the first change. If you then occasionally need more keys, press
  4183. @kbd{C-c} to turn off auto-exit for the current tag selection process
  4184. (in effect: start selection with @kbd{C-c C-c C-c} instead of @kbd{C-c
  4185. C-c}). If you set the variable to the value @code{expert}, the special
  4186. window is not even shown for single-key tag selection, it comes up only

  4214. @node Properties and Columns, Dates and Times, Tags, Top
  4215. @chapter Properties and columns
  4216. @cindex properties
  4217. A property is a key-value pair associated with an entry. Properties can be
  4218. set so they are associated with a single entry, with every entry in a tree,
  4219. or with every entry in an Org mode file.
  4220. There are two main applications for properties in Org mode. First,
  4221. properties are like tags, but with a value. Imagine maintaining a file where
  4222. you document bugs and plan releases for a piece of software. Instead of
  4223. using tags like @code{:release_1:}, @code{:release_2:}, you can use a
  4224. property, say @code{:Release:}, that in different subtrees has different
  4225. values, such as @code{1.0} or @code{2.0}. Second, you can use properties to
  4226. implement (very basic) database capabilities in an Org buffer. Imagine
  4227. keeping track of your music CDs, where properties could be things such as the
  4228. album, artist, date of release, number of tracks, and so on.
  4229. Properties can be conveniently edited and viewed in column view
  4230. (@pxref{Column view}).

  4243. Properties are key-value pairs. When they are associated with a single entry
  4244. or with a tree they need to be inserted into a special
  4245. drawer (@pxref{Drawers}) with the name @code{PROPERTIES}. Each property
  4246. is specified on a single line, with the key (surrounded by colons)
  4247. first, and the value after it. Here is an example:
  4248. @example
  4249. * CD collection
  4250. ** Classic
  4251. *** Goldberg Variations
  4252. :PROPERTIES:
  4253. :Title: Goldberg Variations

  4259. @end example
  4260. Depending on the value of @code{org-use-property-inheritance}, a property set
  4261. this way will either be associated with a single entry, or the sub-tree
  4262. defined by the entry, see @ref{Property inheritance}.
  4263. You may define the allowed values for a particular property @samp{:Xyz:}
  4264. by setting a property @samp{:Xyz_ALL:}. This special property is
  4265. @emph{inherited}, so if you set it in a level 1 entry, it will apply to
  4266. the entire tree. When allowed values are defined, setting the
  4267. corresponding property becomes easier and is less prone to typing
  4268. errors. For the example with the CD collection, we can predefine
  4269. publishers and the number of disks in a box like this:
  4270. @example
  4271. * CD collection
  4272. :PROPERTIES:
  4273. :NDisks_ALL: 1 2 3 4
  4274. :Publisher_ALL: "Deutsche Grammophon" Philips EMI
  4275. :END:
  4276. @end example
  4277. If you want to set properties that can be inherited by any entry in a
  4278. file, use a line like
  4279. @cindex property, _ALL
  4280. @cindex #+PROPERTY
  4281. @example
  4282. #+PROPERTY: NDisks_ALL 1 2 3 4
  4283. @end example
  4284. If you want to add to the value of an existing property, append a @code{+} to
  4285. the property name. The following results in the property @code{var} having
  4286. the value ``foo=1 bar=2''.
  4287. @cindex property, +
  4288. @example
  4289. #+PROPERTY: var foo=1
  4290. #+PROPERTY: var+ bar=2
  4291. @end example
  4292. It is also possible to add to the values of inherited properties. The
  4293. following results in the @code{genres} property having the value ``Classic
  4294. Baroque'' under the @code{Goldberg Variations} subtree.
  4295. @cindex property, +

  4417. @table @kbd
  4418. @orgkey{C-c / p}
  4419. Create a sparse tree based on the value of a property. This first
  4420. prompts for the name of a property, and then for a value. A sparse tree
  4421. is created with all entries that define this property with the given
  4422. value. If you enclose the value in curly braces, it is interpreted as
  4423. a regular expression and matched against the property values.

  4430. The outline structure of Org mode documents lends itself to an
  4431. inheritance model of properties: if the parent in a tree has a certain
  4432. property, the children can inherit this property. Org mode does not
  4433. turn this on by default, because it can slow down property searches
  4434. significantly and is often not needed. However, if you find inheritance
  4435. useful, you can turn it on by setting the variable
  4436. @code{org-use-property-inheritance}. It may be set to @code{t} to make
  4437. all properties inherited from the parent, to a list of properties
  4438. that should be inherited, or to a regular expression that matches
  4439. inherited properties. If a property has the value @samp{nil}, this is
  4440. interpreted as an explicit undefine of the property, so that inheritance
  4441. search will stop at this value and return @code{nil}.
  4442. Org mode has a few properties for which inheritance is hard-coded, at
  4443. least for the special applications for which they are used:
  4444. @cindex property, COLUMNS
  4445. @table @code
  4446. @item COLUMNS
  4447. The @code{:COLUMNS:} property defines the format of column view
  4448. (@pxref{Column view}). It is inherited in the sense that the level
  4449. where a @code{:COLUMNS:} property is defined is used as the starting
  4450. point for a column view table, independently of the location in the
  4451. subtree from where columns view is turned on.
  4452. @item CATEGORY
  4453. @cindex property, CATEGORY
  4454. For agenda view, a category set through a @code{:CATEGORY:} property
  4455. applies to the entire subtree.
  4456. @item ARCHIVE
  4457. @cindex property, ARCHIVE
  4458. For archiving, the @code{:ARCHIVE:} property may define the archive
  4459. location for the entire subtree (@pxref{Moving subtrees}).
  4460. @item LOGGING
  4461. @cindex property, LOGGING
  4462. The LOGGING property may define logging settings for an entry or a
  4463. subtree (@pxref{Tracking TODO state changes}).
  4464. @end table
  4465. @node Column view, Property API, Property inheritance, Properties and Columns
  4466. @section Column view
  4467. A great way to view and edit properties in an outline tree is
  4468. @emph{column view}. In column view, each outline node is turned into a
  4469. table row. Columns in this table provide access to properties of the
  4470. entries. Org mode implements columns by overlaying a tabular structure
  4471. over the headline of each item. While the headlines have been turned
  4472. into a table row, you can still change the visibility of the outline
  4473. tree. For example, you get a compact table by switching to CONTENTS
  4474. view (@kbd{S-@key{TAB} S-@key{TAB}}, or simply @kbd{c} while column view
  4475. is active), but you can still open, read, and edit the entry below each
  4476. headline. Or, you can switch to column view after executing a sparse
  4477. tree command and in this way get a table only for the selected items.
  4478. Column view also works in agenda buffers (@pxref{Agenda Views}) where
  4479. queries have collected selected items, possibly from a number of files.

  4499. @example
  4500. #+COLUMNS: %25ITEM %TAGS %PRIORITY %TODO
  4501. @end example
  4502. To specify a format that only applies to a specific tree, add a
  4503. @code{:COLUMNS:} property to the top node of that tree, for example:
  4504. @example
  4505. ** Top node for columns view

  4508. :END:
  4509. @end example
  4510. If a @code{:COLUMNS:} property is present in an entry, it defines columns
  4511. for the entry itself, and for the entire subtree below it. Since the
  4512. column definition is part of the hierarchical structure of the document,
  4513. you can define columns on level 1 that are general enough for all
  4514. sublevels, and more specific columns further down, when you edit a
  4515. deeper part of the tree.
  4516. @node Column attributes, , Scope of column definitions, Defining columns

  4522. @end example
  4523. @noindent
  4524. Except for the percent sign and the property name, all items are

  4526. @example
  4527. @var{width} @r{An integer specifying the width of the column in characters.}
  4528. @r{If omitted, the width will be determined automatically.}

  4553. @{est+@} @r{Add low-high estimates.}
  4554. @end example
  4555. @noindent
  4556. Be aware that you can only have one summary type for any property you
  4557. include. Subsequent columns referencing the same property will all display the
  4558. same summary information.
  4559. The @code{est+} summary type requires further explanation. It is used for
  4560. combining estimates, expressed as low-high ranges. For example, instead
  4561. of estimating a particular task will take 5 days, you might estimate it as
  4562. 5-6 days if you're fairly confident you know how much work is required, or
  4563. 1-10 days if you don't really know what needs to be done. Both ranges
  4564. average at 5.5 days, but the first represents a more predictable delivery.
  4565. When combining a set of such estimates, simply adding the lows and highs
  4566. produces an unrealistically wide result. Instead, @code{est+} adds the
  4567. statistical mean and variance of the sub-tasks, generating a final estimate
  4568. from the sum. For example, suppose you had ten tasks, each of which was
  4569. estimated at 0.5 to 2 days of work. Straight addition produces an estimate
  4570. of 5 to 20 days, representing what to expect if everything goes either
  4571. extremely well or extremely poorly. In contrast, @code{est+} estimates the
  4572. full job more realistically, at 10-15 days.
  4573. Here is an example for a complete columns definition, along with allowed
  4574. values.
  4575. @example
  4576. :COLUMNS: %25ITEM %9Approved(Approved?)@{X@} %Owner %11Status \@footnote{Please note that the COLUMNS definition must be on a single line---it is wrapped here only because of formatting constraints.}
  4577. %10Time_Estimate@{:@} %CLOCKSUM %CLOCKSUM_T
  4578. :Owner_ALL: Tammy Mark Karl Lisa Don
  4579. :Status_ALL: "In progress" "Not started yet" "Finished" ""
  4580. :Approved_ALL: "[ ]" "[X]"
  4581. @end example
  4582. @noindent
  4583. The first column, @samp{%25ITEM}, means the first 25 characters of the
  4584. item itself, i.e.@: of the headline. You probably always should start the
  4585. column definition with the @samp{ITEM} specifier. The other specifiers
  4586. create columns @samp{Owner} with a list of names as allowed values, for
  4587. @samp{Status} with four different possible values, and for a checkbox
  4588. field @samp{Approved}. When no width is given after the @samp{%}
  4589. character, the column will be exactly as wide as it needs to be in order
  4590. to fully display all values. The @samp{Approved} column does have a
  4591. modified title (@samp{Approved?}, with a question mark). Summaries will
  4592. be created for the @samp{Time_Estimate} column by adding time duration
  4593. expressions like HH:MM, and for the @samp{Approved} column, by providing
  4594. an @samp{[X]} status if all children have been checked. The
  4595. @samp{CLOCKSUM} and @samp{CLOCKSUM_T} columns are special, they lists the
  4596. sums of CLOCK intervals in the subtree, either for all clocks or just for
  4597. today.

  4655. @subsection Capturing column view
  4656. Since column view is just an overlay over a buffer, it cannot be
  4657. exported or printed directly. If you want to capture a column view, use
  4658. a @code{columnview} dynamic block (@pxref{Dynamic blocks}). The frame
  4659. of this block looks like this:
  4660. @cindex #+BEGIN, columnview
  4661. @example
  4662. * The column view
  4663. #+BEGIN: columnview :hlines 1 :id "label"
  4664. #+END:
  4665. @end example
  4666. @noindent This dynamic block has the following parameters:
  4667. @table @code
  4668. @item :id
  4669. This is the most important parameter. Column view is a feature that is
  4670. often localized to a certain (sub)tree, and the capture block might be
  4671. at a different location in the file. To identify the tree whose view to
  4672. capture, you can use 4 values:
  4673. @cindex property, ID
  4674. @example
  4675. local @r{use the tree in which the capture block is located}
  4676. global @r{make a global view, including all headings in the file}
  4677. "file:@var{path-to-file}"
  4678. @r{run column view at the top of this file}
  4679. "@var{ID}" @r{call column view in the tree that has an @code{:ID:}}
  4680. @r{property with the value @i{label}. You can use}
  4681. @r{@kbd{M-x org-id-copy} to create a globally unique ID for}
  4682. @r{the current entry and copy it to the kill-ring.}
  4683. @end example
  4684. @item :hlines
  4685. When @code{t}, insert an hline after every line. When a number @var{N}, insert
  4686. an hline before each headline with level @code{<= @var{N}}.
  4687. @item :vlines
  4688. When set to @code{t}, force column groups to get vertical lines.
  4689. @item :maxlevel
  4690. When set to a number, don't capture entries below this level.
  4691. @item :skip-empty-rows
  4692. When set to @code{t}, skip rows where the only non-empty specifier of the
  4693. column view is @code{ITEM}.
  4694. @end table
  4695. @noindent
  4696. The following commands insert or update the dynamic block:
  4697. @table @kbd
  4698. @orgcmd{C-c C-x i,org-insert-columns-dblock}
  4699. Insert a dynamic block capturing a column view. You will be prompted
  4700. for the scope or ID of the view.
  4701. @orgcmdkkc{C-c C-c,C-c C-x C-u,org-dblock-update}
  4702. Update dynamic block at point. The cursor needs to be in the
  4703. @code{#+BEGIN} line of the dynamic block.
  4704. @orgcmd{C-u C-c C-x C-u,org-update-all-dblocks}
  4705. Update all dynamic blocks (@pxref{Dynamic blocks}). This is useful if
  4706. you have several clock table blocks, column-capturing blocks or other dynamic
  4707. blocks in a buffer.
  4708. @end table
  4709. You can add formulas to the column view table and you may add plotting
  4710. instructions in front of the table---these will survive an update of the
  4711. block. If there is a @code{#+TBLFM:} after the table, the table will
  4712. actually be recalculated automatically after an update.
  4713. An alternative way to capture and process property values into a table is
  4714. provided by Eric Schulte's @file{org-collector.el} which is a contributed
  4715. package@footnote{Contributed packages are not part of Emacs, but are

  4756. A timestamp is a specification of a date (possibly with a time or a range of
  4757. times) in a special format, either @samp{<2003-09-16 Tue>}@footnote{In this
  4758. simplest form, the day name is optional when you type the date yourself.
  4759. However, any dates inserted or modified by Org will add that day name, for
  4760. reading convenience.} or @samp{<2003-09-16 Tue 09:39>} or @samp{<2003-09-16
  4761. Tue 12:00-12:30>}@footnote{This is inspired by the standard ISO 8601
  4762. date/time format. To use an alternative format, see @ref{Custom time
  4763. format}.}. A timestamp can appear anywhere in the headline or body of an Org
  4764. tree entry. Its presence causes entries to be shown on specific dates in the
  4765. agenda (@pxref{Weekly/daily agenda}). We distinguish:
  4766. @table @var
  4767. @item Plain timestamp; Event; Appointment
  4768. @cindex timestamp
  4769. @cindex appointment
  4770. A simple timestamp just assigns a date/time to an item. This is just
  4771. like writing down an appointment or event in a paper agenda. In the
  4772. timeline and agenda displays, the headline of an entry associated with a
  4773. plain timestamp will be shown exactly on that date.
  4774. @example
  4775. * Meet Peter at the movies
  4776. <2006-11-01 Wed 19:15>
  4777. * Discussion on climate change

  4779. @end example
  4780. @item Timestamp with repeater interval
  4781. @cindex timestamp, with repeater interval
  4782. A timestamp may contain a @emph{repeater interval}, indicating that it
  4783. applies not only on the given date, but again and again after a certain
  4784. interval of N days (d), weeks (w), months (m), or years (y). The
  4785. following will show up in the agenda every Wednesday:
  4786. @example
  4787. * Pick up Sam at school
  4788. <2007-05-16 Wed 12:30 +1w>
  4789. @end example
  4790. @item Diary-style sexp entries
  4791. For more complex date specifications, Org mode supports using the special
  4792. sexp diary entries implemented in the Emacs calendar/diary
  4793. package@footnote{When working with the standard diary sexp functions, you
  4794. need to be very careful with the order of the arguments. That order depend
  4795. evilly on the variable @code{calendar-date-style} (or, for older Emacs
  4796. versions, @code{european-calendar-style}). For example, to specify a date
  4797. December 12, 2005, the call might look like @code{(diary-date 12 1 2005)} or
  4798. @code{(diary-date 1 12 2005)} or @code{(diary-date 2005 12 1)}, depending on
  4799. the settings. This has been the source of much confusion. Org mode users
  4800. can resort to special versions of these functions like @code{org-date} or
  4801. @code{org-anniversary}. These work just like the corresponding @code{diary-}
  4802. functions, but with stable ISO order of arguments (year, month, day) wherever
  4803. applicable, independent of the value of @code{calendar-date-style}.}. For
  4804. example with optional time
  4805. @example
  4806. * 22:00-23:00 The nerd meeting on every 2nd Thursday of the month
  4807. <%%(org-float t 4 2)>

  4809. @item Time/Date range
  4810. @cindex timerange
  4811. @cindex date range
  4812. Two timestamps connected by @samp{--} denote a range. The headline
  4813. will be shown on the first and last day of the range, and on any dates
  4814. that are displayed and fall in the range. Here is an example:
  4815. @example
  4816. ** Meeting in Amsterdam
  4817. <2004-08-23 Mon>--<2004-08-26 Thu>
  4818. @end example
  4819. @item Inactive timestamp
  4820. @cindex timestamp, inactive
  4821. @cindex inactive timestamp
  4822. Just like a plain timestamp, but with square brackets instead of
  4823. angular ones. These timestamps are inactive in the sense that they do
  4824. @emph{not} trigger an entry to show up in the agenda.

  4901. When Org mode prompts for a date/time, the default is shown in default
  4902. date/time format, and the prompt therefore seems to ask for a specific
  4903. format. But it will in fact accept any string containing some date and/or
  4904. time information, and it is really smart about interpreting your input. You
  4905. can, for example, use @kbd{C-y} to paste a (possibly multi-line) string
  4906. copied from an email message. Org mode will find whatever information is in
  4907. there and derive anything you have not specified from the @emph{default date
  4908. and time}. The default is usually the current date and time, but when
  4909. modifying an existing timestamp, or when entering the second stamp of a
  4910. range, it is taken from the stamp in the buffer. When filling in
  4911. information, Org mode assumes that most of the time you will want to enter a
  4912. date in the future: if you omit the month/year and the given day/month is
  4913. @i{before} today, it will assume that you mean a future date@footnote{See the
  4914. variable @code{org-read-date-prefer-future}. You may set that variable to
  4915. the symbol @code{time} to even make a time before now shift the date to
  4916. tomorrow.}. If the date has been automatically shifted into the future, the
  4917. time prompt will show this with @samp{(=>F).}
  4918. For example, let's assume that today is @b{June 13, 2006}. Here is how
  4919. various inputs will be interpreted, the items filled in by Org mode are
  4920. in @b{bold}.
  4921. @example
  4922. 3-2-5 @result{} 2003-02-05

  4935. 2012-w04-5 @result{} Same as above
  4936. @end example
  4937. Furthermore you can specify a relative date by giving, as the
  4938. @emph{first} thing in the input: a plus/minus sign, a number and a

  5171. Some tasks need to be repeated again and again. Org mode helps to
  5172. organize such tasks using a so-called repeater in a DEADLINE, SCHEDULED,
  5173. or plain timestamp. In the following example
  5174. @example
  5175. ** TODO Pay the rent
  5176. DEADLINE: <2005-10-01 Sat +1m>
  5177. @end example
  5178. @noindent
  5179. the @code{+1m} is a repeater; the intended interpretation is that the task
  5180. has a deadline on <2005-10-01> and repeats itself every (one) month starting
  5181. from that time. You can use yearly, monthly, weekly, daily and hourly repeat
  5182. cookies by using the @code{y/w/m/d/h} letters. If you need both a repeater
  5183. and a special warning period in a deadline entry, the repeater should come
  5184. first and the warning period last: @code{DEADLINE: <2005-10-01 Sat +1m -3d>}.
  5185. @vindex org-todo-repeat-to-state
  5186. Deadlines and scheduled items produce entries in the agenda when they are
  5187. over-due, so it is important to be able to mark such an entry as completed
  5188. once you have done so. When you mark a DEADLINE or a SCHEDULE with the TODO
  5189. keyword DONE, it will no longer produce entries in the agenda. The problem
  5190. with this is, however, that then also the @emph{next} instance of the
  5191. repeated entry will not be active. Org mode deals with this in the following
  5192. way: When you try to mark such an entry DONE (using @kbd{C-c C-t}), it will
  5193. shift the base date of the repeating timestamp by the repeater interval, and
  5194. immediately set the entry state back to TODO@footnote{In fact, the target
  5195. state is taken from, in this sequence, the @code{REPEAT_TO_STATE} property or
  5196. the variable @code{org-todo-repeat-to-state}. If neither of these is
  5197. specified, the target state defaults to the first state of the TODO state
  5198. sequence.}. In the example above, setting the state to DONE would actually
  5199. switch the date like this:
  5200. @example
  5201. ** TODO Pay the rent
  5202. DEADLINE: <2005-11-01 Tue +1m>
  5203. @end example
  5204. @vindex org-log-repeat
  5205. A timestamp@footnote{You can change this using the option
  5206. @code{org-log-repeat}, or the @code{#+STARTUP} options @code{logrepeat},
  5207. @code{lognoterepeat}, and @code{nologrepeat}. With @code{lognoterepeat}, you
  5208. will also be prompted for a note.} will be added under the deadline, to keep
  5209. a record that you actually acted on the previous instance of this deadline.
  5210. As a consequence of shifting the base date, this entry will no longer be
  5211. visible in the agenda when checking past dates, but all future instances
  5212. will be visible.
  5213. With the @samp{+1m} cookie, the date shift will always be exactly one
  5214. month. So if you have not paid the rent for three months, marking this
  5215. entry DONE will still keep it as an overdue deadline. Depending on the
  5216. task, this may not be the best way to handle it. For example, if you
  5217. forgot to call your father for 3 weeks, it does not make sense to call
  5218. him 3 times in a single day to make up for it. Finally, there are tasks
  5219. like changing batteries which should always repeat a certain time
  5220. @i{after} the last time you did it. For these tasks, Org mode has
  5221. special repeaters @samp{++} and @samp{.+}. For example:
  5222. @example
  5223. ** TODO Call Father
  5224. DEADLINE: <2008-02-10 Sun ++1w>
  5225. Marking this DONE will shift the date by at least one week,
  5226. but also by as many weeks as it takes to get this date into
  5227. the future. However, it stays on a Sunday, even if you called
  5228. and marked it done on Saturday.
  5229. ** TODO Check the batteries in the smoke detectors
  5230. DEADLINE: <2005-11-01 Tue .+1m>
  5231. Marking this DONE will shift the date to one month after
  5232. today.
  5233. @end example
  5234. You may have both scheduling and deadline information for a specific
  5235. task---just make sure that the repeater intervals on both are the same.
  5236. An alternative to using a repeater is to create a number of copies of a task
  5237. subtree, with dates shifted in each copy. The command @kbd{C-c C-x c} was
  5238. created for this purpose, it is described in @ref{Structure editing}.

  5329. them with @kbd{S-@key{cursor}} keys, the update is automatic.
  5330. @orgcmd{C-S-@key{up/down},org-clock-timestamps-up/down}

  5332. clock duration keeps the same.
  5333. @orgcmd{S-M-@key{up/down},org-timestamp-up/down}
  5334. On @code{CLOCK} log lines, increase/decrease the timestamp at point and
  5335. the one of the previous (or the next clock) timestamp by the same duration.
  5336. For example, if you hit @kbd{S-M-@key{up}} to increase a clocked-out timestamp
  5337. by five minutes, then the clocked-in timestamp of the next clock will be
  5338. increased by five minutes.
  5339. @orgcmd{C-c C-t,org-todo}

  5495. @cindex idle, resolve, dangling
  5496. If you clock in on a work item, and then walk away from your
  5497. computer---perhaps to take a phone call---you often need to ``resolve'' the
  5498. time you were away by either subtracting it from the current clock, or
  5499. applying it to another one.
  5500. @vindex org-clock-idle-time
  5501. By customizing the variable @code{org-clock-idle-time} to some integer, such
  5502. as 10 or 15, Emacs can alert you when you get back to your computer after
  5503. being idle for that many minutes@footnote{On computers using Mac OS X,
  5504. idleness is based on actual user idleness, not just Emacs' idle time. For
  5505. X11, you can install a utility program @file{x11idle.c}, available in the
  5506. @code{contrib/scripts} directory of the Org git distribution, to get the same
  5507. general treatment of idleness. On other systems, idle time refers to Emacs
  5508. idle time only.}, and ask what you want to do with the idle time. There will
  5509. be a question waiting for you when you get back, indicating how much idle
  5510. time has passed (constantly updated with the current amount), as well as a
  5511. set of choices to correct the discrepancy:
  5512. @table @kbd
  5513. @item k
  5514. To keep some or all of the minutes and stay clocked in, press @kbd{k}. Org
  5515. will ask how many of the minutes to keep. Press @key{RET} to keep them all,
  5516. effectively changing nothing, or enter a number to keep that many minutes.
  5517. @item K
  5518. If you use the shift key and press @kbd{K}, it will keep however many minutes
  5519. you request and then immediately clock out of that task. If you keep all of
  5520. the minutes, this is the same as just clocking out of the current task.
  5521. @item s
  5522. To keep none of the minutes, use @kbd{s} to subtract all the away time from
  5523. the clock, and then check back in from the moment you returned.
  5524. @item S
  5525. To keep none of the minutes and just clock out at the start of the away time,
  5526. use the shift key and press @kbd{S}. Remember that using shift will always
  5527. leave you clocked out, no matter which option you choose.
  5528. @item C
  5529. To cancel the clock altogether, use @kbd{C}. Note that if instead of
  5530. canceling you subtract the away time, and the resulting clock amount is less
  5531. than a minute, the clock will still be canceled rather than clutter up the
  5532. log with an empty entry.
  5533. @end table
  5534. What if you subtracted those away minutes from the current clock, and now
  5535. want to apply them to a new clock? Simply clock in to any task immediately
  5536. after the subtraction. Org will notice that you have subtracted time ``on
  5537. the books'', so to speak, and will ask if you want to apply those minutes to
  5538. the next task you clock in on.
  5539. There is one other instance when this clock resolution magic occurs. Say you
  5540. were clocked in and hacking away, and suddenly your cat chased a mouse who
  5541. scared a hamster that crashed into your UPS's power button! You suddenly
  5542. lose all your buffers, but thanks to auto-save you still have your recent Org
  5543. mode changes, including your last clock in.
  5544. If you restart Emacs and clock into any task, Org will notice that you have a
  5545. dangling clock which was never clocked out from your last session. Using
  5546. that clock's starting time as the beginning of the unaccounted-for period,
  5547. Org will ask how you want to resolve that time. The logic and behavior is
  5548. identical to dealing with away time due to idleness; it is just happening due
  5549. to a recovery event rather than a set amount of idle time.
  5550. You can also check all the files visited by your Org agenda for dangling
  5551. clocks at any time using @kbd{M-x org-resolve-clocks RET} (or @kbd{C-c C-x C-z}).
  5552. @subsubheading Continuous clocking
  5553. @cindex continuous clocking
  5554. @vindex org-clock-continuously
  5555. You may want to start clocking from the time when you clocked out the
  5556. previous task. To enable this systematically, set @code{org-clock-continuously}
  5557. to @code{t}. Each time you clock in, Org retrieves the clock-out time of the
  5558. last clocked entry for this session, and start the new clock from there.
  5559. If you only want this from time to time, use three universal prefix arguments
  5560. with @code{org-clock-in} and two @kbd{C-u C-u} with @code{org-clock-in-last}.

  5565. @vindex org-effort-property
  5566. If you want to plan your work in a very detailed way, or if you need to
  5567. produce offers with quotations of the estimated work effort, you may want to
  5568. assign effort estimates to entries. If you are also clocking your work, you
  5569. may later want to compare the planned effort with the actual working time, a
  5570. great way to improve planning estimates. Effort estimates are stored in a
  5571. special property @samp{Effort}@footnote{You may change the property being
  5572. used with the variable @code{org-effort-property}.}. You can set the effort
  5573. for an entry with the following commands:
  5574. @table @kbd
  5575. @orgcmd{C-c C-x e,org-set-effort}
  5576. Set the effort estimate for the current entry. With a numeric prefix
  5577. argument, set it to the Nth allowed value (see below). This command is also
  5578. accessible from the agenda with the @kbd{e} key.
  5579. @orgcmd{C-c C-x C-e,org-clock-modify-effort-estimate}
  5580. Modify the effort estimate of the item currently being clocked.
  5581. @end table
  5582. Clearly the best way to work with effort estimates is through column view
  5583. (@pxref{Column view}). You should start by setting up discrete values for
  5584. effort estimates, and a @code{COLUMNS} format that displays these values
  5585. together with clock sums (if you want to clock your time). For a specific
  5586. buffer you can use
  5587. @example
  5588. #+PROPERTY: Effort_ALL 0 0:10 0:30 1:00 2:00 3:00 4:00 5:00 6:00 7:00

  5591. @noindent
  5592. @vindex org-global-properties
  5593. @vindex org-columns-default-format
  5594. or, even better, you can set up these values globally by customizing the
  5595. variables @code{org-global-properties} and @code{org-columns-default-format}.
  5596. In particular if you want to use this setup also in the agenda, a global
  5597. setup may be advised.
  5598. The way to assign estimates to individual items is then to switch to column
  5599. mode, and to use @kbd{S-@key{right}} and @kbd{S-@key{left}} to change the
  5600. value. The values you enter will immediately be summed up in the hierarchy.
  5601. In the column next to it, any clocked time will be displayed.
  5602. @vindex org-agenda-columns-add-appointments-to-effort-sum
  5603. If you switch to column view in the daily/weekly agenda, the effort column
  5604. will summarize the estimated work effort for each day@footnote{Please note
  5605. the pitfalls of summing hierarchical data in a flat list (@pxref{Agenda
  5606. column view}).}, and you can use this to find space in your schedule. To get
  5607. an overview of the entire part of the day that is committed, you can set the
  5608. option @code{org-agenda-columns-add-appointments-to-effort-sum}. The
  5609. appointments on a day that take place over a specified time interval will
  5610. then also be added to the load estimate of the day.
  5611. Effort estimates can be used in secondary agenda filtering that is triggered
  5612. with the @kbd{/} key in the agenda (@pxref{Agenda commands}). If you have
  5613. these estimates defined consistently, two or three key presses will narrow
  5614. down the list to stuff that fits into an available time slot.

  5640. Stop the timer. After this, you can only start a new timer, not continue the

  5648. prefix argument @kbd{C-u C-u}, change all timer strings in the active region

  5683. Org's method for capturing new items is heavily inspired by John Wiegley
  5684. excellent remember package. Up to version 6.36 Org used a special setup
  5685. for @file{remember.el}. @file{org-remember.el} is still part of Org mode for
  5686. backward compatibility with existing setups. You can find the documentation
  5687. for org-remember at @url{http://orgmode.org/org-remember.pdf}.
  5688. The new capturing setup described here is preferred and should be used by new
  5689. users. To convert your @code{org-remember-templates}, run the command
  5690. @example
  5691. @kbd{M-x org-capture-import-remember-templates @key{RET}}
  5692. @end example
  5693. @noindent and then customize the new variable with @kbd{M-x
  5694. customize-variable org-capture-templates}, check the result, and save the
  5695. customization. You can then use both remember and capture until
  5696. you are familiar with the new mechanism.
  5697. Capture lets you quickly store notes with little interruption of your work
  5698. flow. The basic process of capturing is very similar to remember, but Org
  5699. does enhance it with templates and more.

  5707. The following customization sets a default target file for notes, and defines
  5708. a global key@footnote{Please select your own key, @kbd{C-c c} is only a
  5709. suggestion.} for capturing new material.
  5710. @vindex org-default-notes-file

  5719. Call the command @code{org-capture}. Note that this keybinding is global and
  5720. not active by default - you need to install it. If you have templates
  5721. @cindex date tree
  5722. defined @pxref{Capture templates}, it will offer these templates for
  5723. selection or use a new Org outline node as the default template. It will
  5724. insert the template into the target file and switch to an indirect buffer
  5725. narrowed to this new node. You may then insert the information you want.
  5726. @orgcmd{C-c C-c,org-capture-finalize}
  5727. Once you have finished entering information into the capture buffer, @kbd{C-c
  5728. C-c} will return you to the window configuration before the capture process,
  5729. so that you can resume your work without further distraction. When called
  5730. with a prefix arg, finalize and then jump to the captured item.
  5731. @orgcmd{C-c C-w,org-capture-refile}
  5732. Finalize the capture process by refiling (@pxref{Refiling notes}) the note to
  5733. a different place. Please realize that this is a normal refiling command
  5734. that will be executed---so the cursor position at the moment you run this
  5735. command is important. If you have inserted a tree with a parent and
  5736. children, first move the cursor back to the parent. Any prefix argument
  5737. given to this command will be passed on to the @code{org-refile} command.
  5738. @orgcmd{C-c C-k,org-capture-kill}
  5739. Abort the capture process and return to the previous state.
