  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
  699. @uref{http://orgmode.org}.

  710. distribution, GNU ELPA installed by the package manager or an XEmacs package,
  711. please skip this section and go directly to @ref{Activation}. To see what
  712. version of Org (if any) is part of your Emacs distribution, type @kbd{M-x
  713. org-version} (if your Emacs distribution does not come with Org, this
  714. function will not be defined).}
  715. Installation of Org mode uses a build system, which is described in more
  716. detail on @uref{http://orgmode.org/worg/dev/org-build-system.html, Worg}.
  717. If you have downloaded Org from the Web as a distribution @file{.zip} or
  718. @file{.tar.gz} archive, you must take the following steps to install it:
  719. @itemize @bullet
  720. @item Unpack the distribution archive.
  721. @item Change into (@code{cd}) the Org directory.
  722. @item Run @code{make help config}
  723. and then check and edit the file @file{local.mk} if the default configuration
  724. does not match your system. You must set the name of the Emacs binary
  725. (likely either @file{emacs} or @file{xemacs}), and the paths to the
  726. directories where local Lisp and Info files will be installed. If the Emacs
  727. binary is not in your path, you must give the full path to the executable.
  728. Avoid spaces in any path names.
  729. @item Run @code{make config}
  730. again to check the configuration.
  731. @item Optionally run @code{make test}
  732. to build Org mode and then run the full testsuite.
  733. @item Run @code{make install} or @code{sudo make install}
  734. to build and install Org mode on your system.
  735. @end itemize
  736. If you use a cloned Git repository, then the procedure is slightly different.
  737. The following description assumes that you are using the @code{master} branch
  738. (where the development is done). You could also use the @code{maint} branch
  739. instead, where the release versions are published, just replace @code{master}
  740. with @code{maint} in the description below.
  741. @itemize @bullet
  742. @item Change into (@code{cd}) the Org repository.
  743. @item Run @code{git checkout master}
  744. to switch to the @code{master} branch of the Org repository.
  745. @item Run @code{make help}
  746. and then check and edit the file @file{local.mk}. You must set the name of
  747. the Emacs binary (likely either @file{emacs} or @file{xemacs}), and the paths
  748. to the directories where local Lisp and Info files will be installed. If the
  749. Emacs binary is not in your path, you must give the full path to the
  750. executable. Avoid spaces in any path names.
  751. @item Run @code{make config}
  752. to check the configuration.
  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).
  798. @example
  799. make install-info
  800. @end example
  801. Then add the following line to @file{.emacs}. It is needed so that
  802. Emacs can autoload functions that are located in files not immediately loaded
  803. when Org mode starts.
  804. @lisp
  805. (require 'org-install)
  806. @end lisp
  807. Do not forget to activate Org as described in the following section.

  819. Since Emacs 22.2, files with the @file{.org} extension use Org mode by
  820. default. If you are using an earlier version of Emacs, add this line to
  821. your @file{.emacs} file:
  822. @lisp
  823. (add-to-list 'auto-mode-alist '("\\.org\\'" . org-mode))
  824. @end lisp
  825. Org mode buffers need font-lock to be turned on - this is the default in
  826. Emacs@footnote{If you don't use font-lock globally, turn it on in Org buffer
  827. with @code{(add-hook 'org-mode-hook 'turn-on-font-lock)}}.
  828. There are compatibility issues between Org mode and some other Elisp
  829. packages, please take the time to check the list (@pxref{Conflicts}).
  830. The four Org commands @command{org-store-link}, @command{org-capture},
  831. @command{org-agenda}, and @command{org-iswitchb} should be accessible through
  832. global keys (i.e.@: anywhere in Emacs, not just in Org buffers). Here are
  833. suggested bindings for these keys, please modify the keys to your own
  834. liking.
  835. @lisp
  836. (global-set-key "\C-cl" 'org-store-link)
  837. (global-set-key "\C-cc" 'org-capture)
  838. (global-set-key "\C-ca" 'org-agenda)
  839. (global-set-key "\C-cb" 'org-iswitchb)
  840. @end lisp
  841. @cindex Org mode, turning on
  842. With this setup, all files with extension @samp{.org} will be put
  843. into Org mode. As an alternative, make the first line of a file look
  844. like this:
  845. @example
  846. MY PROJECTS -*- mode: org; -*-
  847. @end example
  848. @vindex org-insert-mode-line-in-empty-file
  849. @noindent which will select Org mode for this buffer no matter what
  850. the file's name is. See also the variable
  851. @code{org-insert-mode-line-in-empty-file}.
  852. Many commands in Org work on the region if the region is @i{active}. To make
  853. use of this, you need to have @code{transient-mark-mode}
  854. (@code{zmacs-regions} in XEmacs) turned on. In Emacs 23 this is the default,
  855. in Emacs 22 you need to do this yourself with
  856. @lisp
  857. (transient-mark-mode 1)
  858. @end lisp
  859. @noindent If you do not like @code{transient-mark-mode}, you can create an
  860. active region by using the mouse to select a region, or pressing
  861. @kbd{C-@key{SPC}} twice before moving the cursor.

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

  1013. @cindex Outline mode
  1014. Org is implemented on top of Outline mode. Outlines allow a
  1015. document to be organized in a hierarchical structure, which (at least
  1016. for me) is the best representation of notes and thoughts. An overview
  1017. of this structure is achieved by folding (hiding) large parts of the
  1018. document to show only the general document structure and the parts
  1019. currently being worked on. Org greatly simplifies the use of
  1020. outlines by compressing the entire show/hide functionality into a single
  1021. command, @command{org-cycle}, which is bound to the @key{TAB} key.

  1027. @vindex org-special-ctrl-k
  1028. @vindex org-ctrl-k-protect-subtree
  1029. Headlines define the structure of an outline tree. The headlines in Org
  1030. start with one or more stars, on the left margin@footnote{See the variables
  1031. @code{org-special-ctrl-a/e}, @code{org-special-ctrl-k}, and
  1032. @code{org-ctrl-k-protect-subtree} to configure special behavior of @kbd{C-a},
  1033. @kbd{C-e}, and @kbd{C-k} in headlines.} @footnote{Clocking only works with
  1034. headings indented less then 30 stars.}. For example:
  1035. @example
  1036. * Top level headline
  1037. ** Second level
  1038. *** 3rd level
  1039. some text
  1040. *** 3rd level
  1041. more text
  1042. * Another top level headline
  1043. @end example
  1044. @noindent Some people find the many stars too noisy and would prefer an
  1045. outline that has whitespace followed by a single star as headline
  1046. starters. @ref{Clean view}, describes a setup to realize this.
  1047. @vindex org-cycle-separator-lines
  1048. An empty line after the end of a subtree is considered part of it and
  1049. will be hidden when the subtree is folded. However, if you leave at
  1050. least two empty lines, one empty line will remain visible after folding
  1051. the subtree, in order to structure the collapsed view. See the
  1052. variable @code{org-cycle-separator-lines} to modify this behavior.

  1215. Insert new heading with same level as current. If the cursor is in a plain
  1216. list item, a new item is created (@pxref{Plain lists}). To force creation of
  1217. a new headline, use a prefix argument. When this command is used in the
  1218. middle of a line, the line is split and the rest of the line becomes the new
  1219. headline@footnote{If you do not want the line to be split, customize the
  1220. variable @code{org-M-RET-may-split-line}.}. If the command is used at the
  1221. beginning of a headline, the new headline is created before the current line.
  1222. If at the beginning of any other line, the content of that line is made the
  1223. new heading. If the command is used at the end of a folded subtree (i.e.@:
  1224. behind the ellipses at the end of a headline), then a headline like the
  1225. current one will be inserted after the end of the subtree.
  1226. @orgcmd{C-@key{RET},org-insert-heading-respect-content}
  1227. Just like @kbd{M-@key{RET}}, except when adding a new heading below the
  1228. current heading, the new heading is placed after the body instead of before
  1229. it. This command works from anywhere in the entry.
  1230. @orgcmd{M-S-@key{RET},org-insert-todo-heading}
  1231. @vindex org-treat-insert-todo-heading-as-state-change

  1234. @orgcmd{C-S-@key{RET},org-insert-todo-heading-respect-content}
  1235. Insert new TODO entry with same level as current heading. Like
  1236. @kbd{C-@key{RET}}, the new headline will be inserted after the current
  1237. subtree.
  1238. @orgcmd{@key{TAB},org-cycle}
  1239. In a new entry with no text yet, the first @key{TAB} demotes the entry to
  1240. become a child of the previous one. The next @key{TAB} makes it a parent,
  1241. and so on, all the way to top level. Yet another @key{TAB}, and you are back
  1242. to the initial level.
  1243. @orgcmd{M-@key{left},org-do-promote}
  1244. Promote current heading by one level.
  1245. @orgcmd{M-@key{right},org-do-demote}
  1246. Demote current heading by one level.
  1247. @orgcmd{M-S-@key{left},org-promote-subtree}
  1248. Promote the current subtree by one level.
  1249. @orgcmd{M-S-@key{right},org-demote-subtree}
  1250. Demote the current subtree by one level.
  1251. @orgcmd{M-S-@key{up},org-move-subtree-up}
  1252. Move subtree up (swap with previous subtree of same
  1253. level).
  1254. @orgcmd{M-S-@key{down},org-move-subtree-down}
  1255. Move subtree down (swap with next subtree of same level).
  1256. @orgcmd{C-c C-x C-w,org-cut-subtree}
  1257. Kill subtree, i.e.@: remove it from buffer but save in kill ring.
  1258. With a numeric prefix argument N, kill N sequential subtrees.
  1259. @orgcmd{C-c C-x M-w,org-copy-subtree}
  1260. Copy subtree to kill ring. With a numeric prefix argument N, copy the N
  1261. sequential subtrees.
  1262. @orgcmd{C-c C-x C-y,org-paste-subtree}
  1263. Yank subtree from kill ring. This does modify the level of the subtree to
  1264. make sure the tree fits in nicely at the yank position. The yank level can
  1265. also be specified with a numeric prefix argument, or by yanking after a
  1266. headline marker like @samp{****}.
  1267. @orgcmd{C-y,org-yank}
  1268. @vindex org-yank-adjusted-subtrees
  1269. @vindex org-yank-folded-subtrees
  1270. Depending on the variables @code{org-yank-adjusted-subtrees} and
  1271. @code{org-yank-folded-subtrees}, Org's internal @code{yank} command will
  1272. paste subtrees folded and in a clever way, using the same command as @kbd{C-c
  1273. C-x C-y}. With the default settings, no level adjustment will take place,
  1274. but the yanked tree will be folded unless doing so would swallow text
  1275. previously visible. Any prefix argument to this command will force a normal
  1276. @code{yank} to be executed, with the prefix passed along. A good way to
  1277. force a normal yank is @kbd{C-u C-y}. If you use @code{yank-pop} after a
  1278. yank, it will yank previous kill items plainly, without adjustment and
  1279. folding.
  1280. @orgcmd{C-c C-x c,org-clone-subtree-with-time-shift}
  1281. Clone a subtree by making a number of sibling copies of it. You will be
  1282. prompted for the number of copies to make, and you can also specify if any
  1283. timestamps in the entry should be shifted. This can be useful, for example,
  1284. to create a number of tasks related to a series of lectures to prepare. For
  1285. more details, see the docstring of the command
  1286. @code{org-clone-subtree-with-time-shift}.
  1287. @orgcmd{C-c C-w,org-refile}
  1288. Refile entry or region to a different location. @xref{Refiling notes}.
  1289. @orgcmd{C-c ^,org-sort}
  1290. Sort same-level entries. When there is an active region, all entries in the
  1291. region will be sorted. Otherwise the children of the current headline are
  1292. sorted. The command prompts for the sorting method, which can be
  1293. alphabetically, numerically, by time (first timestamp with active preferred,
  1294. creation time, scheduled time, deadline time), by priority, by TODO keyword
  1295. (in the sequence the keywords have been defined in the setup) or by the value
  1296. of a property. Reverse sorting is possible as well. You can also supply
  1297. your own function to extract the sorting key. With a @kbd{C-u} prefix,
  1298. sorting will be case-sensitive.
  1299. @orgcmd{C-x n s,org-narrow-to-subtree}
  1300. Narrow buffer to current subtree.
  1301. @orgcmd{C-x n b,org-narrow-to-block}
  1302. Narrow buffer to current block.
  1303. @orgcmd{C-x n w,widen}
  1304. Widen buffer to remove narrowing.
  1305. @orgcmd{C-c *,org-toggle-heading}
  1306. Turn a normal line or plain list item into a headline (so that it becomes a
  1307. subheading at its location). Also turn a headline into a normal line by
  1308. removing the stars. If there is an active region, turn all lines in the
  1309. region into headlines. If the first line in the region was an item, turn
  1310. only the item lines into headlines. Finally, if the first line is a
  1311. headline, remove the stars from all headlines in the region.

  1316. When there is an active region (Transient Mark mode), promotion and
  1317. demotion work on all headlines in the region. To select a region of
  1318. headlines, it is best to place both point and mark at the beginning of a
  1319. line, mark at the beginning of the first headline, and point at the line
  1320. just after the last headline to change. Note that when the cursor is
  1321. inside a table (@pxref{Tables}), the Meta-Cursor keys have different

  1333. An important feature of Org mode is the ability to construct @emph{sparse
  1334. trees} for selected information in an outline tree, so that the entire
  1335. document is folded as much as possible, but the selected information is made
  1336. visible along with the headline structure above it@footnote{See also the
  1337. variables @code{org-show-hierarchy-above}, @code{org-show-following-heading},
  1338. @code{org-show-siblings}, and @code{org-show-entry-below} for detailed
  1339. control on how much context is shown around each match.}. Just try it out
  1340. and you will see immediately how it works.
  1341. Org mode contains several commands creating such trees, all these
  1342. commands can be accessed through a dispatcher:
  1343. @table @asis
  1344. @orgcmd{C-c /,org-sparse-tree}
  1345. This prompts for an extra key to select a sparse-tree creating command.
  1346. @orgcmd{C-c / r,org-occur}
  1347. @vindex org-remove-highlights-with-change
  1348. Prompts for a regexp and shows a sparse tree with all matches. If
  1349. the match is in a headline, the headline is made visible. If the match is in
  1350. the body of an entry, headline and body are made visible. In order to
  1351. provide minimal context, also the full hierarchy of headlines above the match
  1352. is shown, as well as the headline following the match. Each match is also
  1353. highlighted; the highlights disappear when the buffer is changed by an
  1354. editing command@footnote{This depends on the option
  1355. @code{org-remove-highlights-with-change}}, or by pressing @kbd{C-c C-c}.
  1356. When called with a @kbd{C-u} prefix argument, previous highlights are kept,
  1357. so several calls to this command can be stacked.
  1358. @orgcmdkkc{M-g n,M-g M-n,next-error}
  1359. Jump to the next sparse tree match in this buffer.
  1360. @orgcmdkkc{M-g p,M-g M-p,previous-error}
  1361. Jump to the previous sparse tree match in this buffer.

  1412. @code{org-plain-list-ordered-item-terminator}.}, such as @samp{1.} or
  1413. @samp{1)}@footnote{You can also get @samp{a.}, @samp{A.}, @samp{a)} and
  1414. @samp{A)} by configuring @code{org-alphabetical-lists}. To minimize
  1415. confusion with normal text, those are limited to one character only. Beyond
  1416. that limit, bullets will automatically fallback to numbers.}. If you want a
  1417. list to start with a different value (e.g.@: 20), start the text of the item
  1418. with @code{[@@20]}@footnote{If there's a checkbox in the item, the cookie
  1419. must be put @emph{before} the checkbox. If you have activated alphabetical
  1420. lists, you can also use counters like @code{[@@b]}.}. Those constructs can
  1421. be used in any item of the list in order to enforce a particular numbering.
  1422. @item
  1423. @emph{Description} list items are unordered list items, and contain the
  1424. separator @samp{ :: } to distinguish the description @emph{term} from the
  1425. description.
  1426. @end itemize
  1427. Items belonging to the same list must have the same indentation on the first
  1428. line. In particular, if an ordered list reaches number @samp{10.}, then the
  1429. 2--digit numbers must be written left-aligned with the other numbers in the
  1430. list. An item ends before the next line that is less or equally indented
  1431. than its bullet/number.
  1432. @vindex org-empty-line-terminates-plain-lists
  1433. A list ends whenever every item has ended, which means before any line less
  1434. or equally indented than items at top level. It also ends before two blank
  1435. lines@footnote{See also @code{org-empty-line-terminates-plain-lists}.}. In
  1436. that case, all items are closed. Here is an example:
  1437. @example
  1438. @group
  1439. ** Lord of the Rings
  1440. My favorite scenes are (in this order)
  1441. 1. The attack of the Rohirrim
  1442. 2. Eowyn's fight with the witch king
  1443. + this was already my favorite scene in the book
  1444. + I really like Miranda Otto.
  1445. 3. Peter Jackson being shot by Legolas
  1446. - on DVD only
  1447. He makes a really funny face when it happens.
  1448. But in the end, no individual scenes matter but the film as a whole.
  1449. Important actors in this film are:
  1450. - @b{Elijah Wood} :: He plays Frodo
  1451. - @b{Sean Austin} :: He plays Sam, Frodo's friend. I still remember
  1452. him very well from his role as Mikey Walsh in @i{The Goonies}.
  1453. @end group
  1454. @end example
  1455. Org supports these lists by tuning filling and wrapping commands to deal with
  1456. them correctly@footnote{Org only changes the filling settings for Emacs. For
  1457. XEmacs, you should use Kyle E. Jones' @file{filladapt.el}. To turn this on,
  1458. put into @file{.emacs}: @code{(require 'filladapt)}}, and by exporting them
  1459. properly (@pxref{Exporting}). Since indentation is what governs the
  1460. structure of these lists, many structural constructs like @code{#+BEGIN_...}
  1461. blocks can be indented to signal that they belong to a particular item.
  1462. @vindex org-list-demote-modify-bullet
  1463. @vindex org-list-indent-offset
  1464. If you find that using a different bullet for a sub-list (than that used for
  1465. the current list-level) improves readability, customize the variable
  1466. @code{org-list-demote-modify-bullet}. To get a greater difference of
  1467. indentation between items and theirs sub-items, customize
  1468. @code{org-list-indent-offset}.
  1469. @vindex org-list-automatic-rules
  1470. The following commands act on items when the cursor is in the first line of
  1471. an item (the line with the bullet or number). Some of them imply the
  1472. application of automatic rules to keep list structure intact. If some of
  1473. these actions get in your way, configure @code{org-list-automatic-rules}
  1474. to disable them individually.

  1477. @cindex cycling, in plain lists
  1478. @vindex org-cycle-include-plain-lists
  1479. Items can be folded just like headline levels. Normally this works only if
  1480. the cursor is on a plain list item. For more details, see the variable
  1481. @code{org-cycle-include-plain-lists}. If this variable is set to
  1482. @code{integrate}, plain list items will be treated like low-level
  1483. headlines. The level of an item is then given by the indentation of the
  1484. bullet/number. Items are always subordinate to real headlines, however; the
  1485. hierarchies remain completely separated. In a new item with no text yet, the
  1486. first @key{TAB} demotes the item to become a child of the previous
  1487. one. Subsequent @key{TAB}s move the item to meaningful levels in the list
  1488. and eventually get it back to its initial position.
  1489. @orgcmd{M-@key{RET},org-insert-heading}
  1490. @vindex org-M-RET-may-split-line
  1491. @vindex org-list-automatic-rules
  1492. Insert new item at current level. With a prefix argument, force a new
  1493. heading (@pxref{Structure editing}). If this command is used in the middle
  1494. of an item, that item is @emph{split} in two, and the second part becomes the
  1495. new item@footnote{If you do not want the item to be split, customize the
  1496. variable @code{org-M-RET-may-split-line}.}. If this command is executed
  1497. @emph{before item's body}, the new item is created @emph{before} the current

  1512. @code{org-list-use-circular-motion}.}, but only if
  1513. @code{org-support-shift-select} is off. If not, you can still use paragraph
  1514. jumping commands like @kbd{C-@key{up}} and @kbd{C-@key{down}} to quite

  1520. Move the item including subitems up/down@footnote{See
  1521. @code{org-liste-use-circular-motion} for a cyclic behavior.} (swap with
  1522. previous/next item of same indentation). If the list is ordered, renumbering

  1530. @kindex M-S-@key{right}
  1531. @item M-S-left
  1532. @itemx M-S-right
  1533. Decrease/increase the indentation of the item, including subitems.
  1534. Initially, the item tree is selected based on current indentation. When
  1535. these commands are executed several times in direct succession, the initially
  1536. selected region is used, even if the new indentation would imply a different
  1537. hierarchy. To use the new hierarchy, break the command chain with a cursor
  1538. motion or so.
  1539. As a special case, using this command on the very first item of a list will
  1540. move the whole list. This behavior can be disabled by configuring
  1541. @code{org-list-automatic-rules}. The global indentation of a list has no
  1542. influence on the text @emph{after} the list.
  1543. @kindex C-c C-c
  1544. @item C-c C-c
  1545. If there is a checkbox (@pxref{Checkboxes}) in the item line, toggle the
  1546. state of the checkbox. In any case, verify bullets and indentation
  1547. consistency in the whole list.
  1548. @kindex C-c -
  1549. @vindex org-plain-list-ordered-item-terminator
  1550. @item C-c -
  1551. Cycle the entire list level through the different itemize/enumerate bullets
  1552. (@samp{-}, @samp{+}, @samp{*}, @samp{1.}, @samp{1)}) or a subset of them,
  1553. depending on @code{org-plain-list-ordered-item-terminator}, the type of list,
  1554. and its indentation. With a numeric prefix argument N, select the Nth bullet
  1555. from this list. If there is an active region when calling this, selected
  1556. text will be changed into an item. With a prefix argument, all lines will be
  1557. converted to list items. If the first line already was a list item, any item
  1558. marker will be removed from the list. Finally, even without an active
  1559. region, a normal line will be converted into a list item.
  1560. @kindex C-c *
  1561. @item C-c *
  1562. Turn a plain list item into a headline (so that it becomes a subheading at
  1563. its location). @xref{Structure editing}, for a detailed explanation.
  1564. @kindex C-c C-*
  1565. @item C-c C-*
  1566. Turn the whole plain list into a subtree of the current heading. Checkboxes
  1567. (@pxref{Checkboxes}) will become TODO (resp. DONE) keywords when unchecked
  1568. (resp. checked).
  1569. @kindex S-@key{left}
  1570. @kindex S-@key{right}
  1571. @item S-left/right
  1572. @vindex org-support-shift-select

  1575. @code{org-support-shift-select}.
  1576. @kindex C-c ^
  1577. @item C-c ^
  1578. Sort the plain list. You will be prompted for the sorting method:

  1602. @end example
  1603. You can interactively insert drawers at point by calling
  1604. @code{org-insert-drawer}, which is bound to @key{C-c C-x d}. With an active
  1605. region, this command will put the region inside the drawer. With a prefix
  1606. argument, this command calls @code{org-insert-property-drawer} and add a
  1607. property drawer right below the current headline. Completion over drawer
  1608. keywords is also possible using @key{M-TAB}.
  1609. Visibility cycling (@pxref{Visibility cycling}) on the headline will hide and
  1610. show the entry, but keep the drawer collapsed to a single line. In order to

  1641. Org mode supports the creation of footnotes. In contrast to the
  1642. @file{footnote.el} package, Org mode's footnotes are designed for work on a
  1643. larger document, not only for one-off documents like emails. The basic
  1644. syntax is similar to the one used by @file{footnote.el}, i.e.@: a footnote is
  1645. defined in a paragraph that is started by a footnote marker in square
  1646. brackets in column 0, no indentation allowed. If you need a paragraph break
  1647. inside a footnote, use the @LaTeX{} idiom @samp{\par}. The footnote reference
  1648. is simply the marker in square brackets, inside text. For example:
  1649. @example
  1650. The Org homepage[fn:1] now looks a lot better than it used to.
  1651. ...
  1652. [fn:1] The link is: http://orgmode.org
  1653. @end example
  1654. Org mode extends the number-based syntax to @emph{named} footnotes and
  1655. optional inline definition. Using plain numbers as markers (as
  1656. @file{footnote.el} does) is supported for backward compatibility, but not
  1657. encouraged because of possible conflicts with @LaTeX{} snippets (@pxref{Embedded
  1658. @LaTeX{}}). Here are the valid references:
  1659. @table @code
  1660. @item [1]
  1661. A plain numeric footnote marker. Compatible with @file{footnote.el}, but not
  1662. recommended because something like @samp{[1]} could easily be part of a code
  1663. snippet.
  1664. @item [fn:name]
  1665. A named footnote reference, where @code{name} is a unique label word, or, for
  1666. simplicity of automatic creation, a number.
  1667. @item [fn:: This is the inline definition of this footnote]
  1668. A @LaTeX{}-like anonymous footnote where the definition is given directly at the
  1669. reference point.
  1670. @item [fn:name: a definition]
  1671. An inline definition of a footnote, which also specifies a name for the note.
  1672. Since Org allows multiple references to the same note, you can then use
  1673. @code{[fn:name]} to create additional references.
  1674. @end table
  1675. @vindex org-footnote-auto-label
  1676. Footnote labels can be created automatically, or you can create names yourself.
  1677. This is handled by the variable @code{org-footnote-auto-label} and its
  1678. corresponding @code{#+STARTUP} keywords. See the docstring of that variable
  1679. for details.
  1680. @noindent The following command handles footnotes:
  1681. @table @kbd
  1682. @kindex C-c C-x f
  1683. @item C-c C-x f
  1684. The footnote action command.
  1685. When the cursor is on a footnote reference, jump to the definition. When it
  1686. is at a definition, jump to the (first) reference.
  1687. @vindex org-footnote-define-inline
  1688. @vindex org-footnote-section
  1689. @vindex org-footnote-auto-adjust

  1692. setting is: @code{#+STARTUP: fninline} or @code{#+STARTUP: nofninline}}, the
  1693. definition will be placed right into the text as part of the reference, or
  1694. separately into the location determined by the variable
  1695. @code{org-footnote-section}.
  1696. When this command is called with a prefix argument, a menu of additional
  1697. options is offered:
  1698. @example
  1699. s @r{Sort the footnote definitions by reference sequence. During editing,}
  1700. @r{Org makes no effort to sort footnote definitions into a particular}
  1701. @r{sequence. If you want them sorted, use this command, which will}

  1738. If you like the intuitive way the Org mode structure editing and list
  1739. formatting works, you might want to use these commands in other modes like
  1740. Text mode or Mail mode as well. The minor mode @code{orgstruct-mode} makes
  1741. this possible. Toggle the mode with @kbd{M-x orgstruct-mode}, or
  1742. turn it on by default, for example in Message mode, with one of:
  1743. @lisp
  1744. (add-hook 'message-mode-hook 'turn-on-orgstruct)
  1745. (add-hook 'message-mode-hook 'turn-on-orgstruct++)
  1746. @end lisp
  1747. When this mode is active and the cursor is on a line that looks to Org like a
  1748. headline or the first line of a list item, most structure editing commands
  1749. will work, even if the same keys normally have different functionality in the
  1750. major mode you are using. If the cursor is not in one of those special
  1751. lines, Orgstruct mode lurks silently in the shadows. When you use
  1752. @code{orgstruct++-mode}, Org will also export indentation and autofill
  1753. settings into that mode, and detect item context after the first line of an
  1754. item.

  1775. is also the column separator@footnote{To insert a vertical bar into a table
  1776. field, use @code{\vert} or, inside a word @code{abc\vert@{@}def}.}. A table
  1777. might look like this:
  1778. @example
  1779. | Name | Phone | Age |
  1780. |-------+-------+-----|
  1781. | Peter | 1234 | 17 |
  1782. | Anna | 4321 | 25 |
  1783. @end example
  1784. A table is re-aligned automatically each time you press @key{TAB} or
  1785. @key{RET} or @kbd{C-c C-c} inside the table. @key{TAB} also moves to
  1786. the next field (@key{RET} to the next row) and creates new table rows
  1787. at the end of the table or before horizontal lines. The indentation
  1788. of the table is set by the first line. Any line starting with
  1789. @samp{|-} is considered as a horizontal separator line and will be
  1790. expanded on the next re-align to span the whole table width. So, to
  1791. create the above table, you would only type
  1792. @example
  1793. |Name|Phone|Age|
  1794. |-
  1795. @end example
  1796. @noindent and then press @key{TAB} to align the table and start filling in

  1801. When typing text into a field, Org treats @key{DEL},
  1802. @key{Backspace}, and all character keys in a special way, so that
  1803. inserting and deleting avoids shifting other fields. Also, when
  1804. typing @emph{immediately after the cursor was moved into a new field
  1805. with @kbd{@key{TAB}}, @kbd{S-@key{TAB}} or @kbd{@key{RET}}}, the
  1806. field is automatically made blank. If this behavior is too
  1807. unpredictable for you, configure the variables
  1808. @code{org-enable-table-editor} and @code{org-table-auto-blank-field}.
  1809. @table @kbd
  1810. @tsubheading{Creation and conversion}
  1811. @orgcmd{C-c |,org-table-create-or-convert-from-region}
  1812. Convert the active region to table. If every line contains at least one
  1813. TAB character, the function assumes that the material is tab separated.
  1814. If every line contains a comma, comma-separated values (CSV) are assumed.
  1815. If not, lines are split at whitespace into fields. You can use a prefix
  1816. argument to force a specific separator: @kbd{C-u} forces CSV, @kbd{C-u
  1817. C-u} forces TAB, and a numeric argument N indicates that at least N
  1818. consecutive spaces, or alternatively a TAB will be the separator.
  1819. @*
  1820. If there is no active region, this command creates an empty Org
  1821. table. But it is easier just to start typing, like
  1822. @kbd{|Name|Phone|Age @key{RET} |- @key{TAB}}.

  1874. between the nearest horizontal separator lines, or the entire table. If
  1875. point is before the first column, you will be prompted for the sorting
  1876. column. If there is an active region, the mark specifies the first line
  1877. and the sorting column, while point should be in the last line to be
  1878. included into the sorting. The command prompts for the sorting type
  1879. (alphabetically, numerically, or by time). When called with a prefix
  1880. argument, alphabetic sorting will be case-sensitive.
  1881. @tsubheading{Regions}
  1882. @orgcmd{C-c C-x M-w,org-table-copy-region}
  1883. Copy a rectangular region from a table to a special clipboard. Point and

  1885. copy just the current field. The process ignores horizontal separator lines.
  1886. @c
  1887. @orgcmd{C-c C-x C-w,org-table-cut-region}

  1894. will be overwritten. If the rectangle does not fit into the present table,
  1895. the table is enlarged as needed. The process ignores horizontal separator
  1896. lines.
  1897. @c
  1898. @orgcmd{M-@key{RET},org-table-wrap-region}
  1899. Split the current field at the cursor position and move the rest to the line
  1900. below. If there is an active region, and both point and mark are in the same
  1901. column, the text in the column is wrapped to minimum width for the given
  1902. number of lines. A numeric prefix argument may be used to change the number
  1903. of desired lines. If there is no region, but you specify a prefix argument,
  1904. the current field is made blank, and the content is appended to the field
  1905. above.

  1912. @orgcmd{C-c +,org-table-sum}
  1913. Sum the numbers in the current column, or in the rectangle defined by
  1914. the active region. The result is shown in the echo area and can
  1915. be inserted with @kbd{C-y}.
  1916. @c
  1917. @orgcmd{S-@key{RET},org-table-copy-down}
  1918. @vindex org-table-copy-increment
  1919. When current field is empty, copy from first non-empty field above. When not
  1920. empty, copy current field down to next row and move cursor along with it.
  1921. Depending on the variable @code{org-table-copy-increment}, integer field
  1922. values will be incremented during copy. Integers that are too large will not
  1923. be incremented. Also, a @code{0} prefix argument temporarily disables the
  1924. increment. This key is also used by shift-selection and related modes
  1925. (@pxref{Conflicts}).
  1926. @tsubheading{Miscellaneous}
  1927. @orgcmd{C-c `,org-table-edit-field}
  1928. Edit the current field in a separate window. This is useful for fields that
  1929. are not fully visible (@pxref{Column width and alignment}). When called with
  1930. a @kbd{C-u} prefix, just make the full field visible, so that it can be
  1931. edited in place. When called with two @kbd{C-u} prefixes, make the editor
  1932. window follow the cursor through the table and always show the current
  1933. field. The follow mode exits automatically when the cursor leaves the table,
  1934. or when you repeat this command with @kbd{C-u C-u C-c `}.
  1935. @c
  1936. @item M-x org-table-import
  1937. Import a file as a table. The table should be TAB or whitespace
  1938. separated. Use, for example, to import a spreadsheet table or data
  1939. from a database, because these programs generally can write
  1940. TAB-separated text files. This command works by inserting the file into
  1941. the buffer and then converting the region to a table. Any prefix
  1942. argument is passed on to the converter, which uses it to determine the
  1943. separator.
  1944. @orgcmd{C-c |,org-table-create-or-convert-from-region}
  1945. Tables can also be imported by pasting tabular text into the Org
  1946. buffer, selecting the pasted text with @kbd{C-x C-x} and then using the
  1947. @kbd{C-c |} command (see above under @i{Creation and conversion}).
  1948. @c
  1949. @item M-x org-table-export
  1950. @findex org-table-export
  1951. @vindex org-table-export-default-format
  1952. Export the table, by default as a TAB-separated file. Use for data
  1953. exchange with, for example, spreadsheet or database programs. The format
  1954. used to export the file can be configured in the variable
  1955. @code{org-table-export-default-format}. You may also use properties
  1956. @code{TABLE_EXPORT_FILE} and @code{TABLE_EXPORT_FORMAT} to specify the file
  1957. name and the format for table export in a subtree. Org supports quite
  1958. general formats for exported tables. The exporter format is the same as the
  1959. format used by Orgtbl radio tables, see @ref{Translator functions}, for a
  1960. detailed description.
  1961. @end table
  1962. If you don't like the automatic table editor because it gets in your
  1963. way on lines which you would like to start with @samp{|}, you can turn
  1964. it off with
  1965. @lisp
  1966. (setq org-enable-table-editor nil)
  1967. @end lisp
  1968. @noindent Then the only table command that still works is
  1969. @kbd{C-c C-c} to do a manual re-align.

  1971. @section Column width and alignment
  1972. @cindex narrow columns in tables
  1973. @cindex alignment in tables
  1974. The width of columns is automatically determined by the table editor. And
  1975. also the alignment of a column is determined automatically from the fraction
  1976. of number-like versus non-number fields in the column.
  1977. Sometimes a single field or a few fields need to carry more text, leading to
  1978. inconveniently wide columns. Or maybe you want to make a table with several
  1979. columns having a fixed width, regardless of content. To set@footnote{This
  1980. feature does not work on XEmacs.} the width of a column, one field anywhere
  1981. in the column may contain just the string @samp{<N>} where @samp{N} is an
  1982. integer specifying the width of the column in characters. The next re-align
  1983. will then set the width of this column to this value.
  1984. @example
  1985. @group
  1986. |---+------------------------------| |---+--------|
  1987. | | | | | <6> |
  1988. | 1 | one | | 1 | one |
  1989. | 2 | two | ----\ | 2 | two |
  1990. | 3 | This is a long chunk of text | ----/ | 3 | This=> |

  1992. |---+------------------------------| |---+--------|
  1993. @end group
  1994. @end example
  1995. @noindent
  1996. Fields that are wider become clipped and end in the string @samp{=>}.
  1997. Note that the full text is still in the buffer but is hidden.
  1998. To see the full text, hold the mouse over the field---a tool-tip window
  1999. will show the full content. To edit such a field, use the command
  2000. @kbd{C-c `} (that is @kbd{C-c} followed by the backquote). This will
  2001. open a new window with the full field. Edit it and finish with @kbd{C-c
  2002. C-c}.
  2003. @vindex org-startup-align-all-tables
  2004. When visiting a file containing a table with narrowed columns, the
  2005. necessary character hiding has not yet happened, and the table needs to
  2006. be aligned before it looks nice. Setting the option
  2007. @code{org-startup-align-all-tables} will realign all tables in a file
  2008. upon visiting, but also slow down startup. You can also set this option
  2009. on a per-file basis with:
  2010. @example
  2011. #+STARTUP: align
  2012. #+STARTUP: noalign
  2013. @end example
  2014. If you would like to overrule the automatic alignment of number-rich columns
  2015. to the right and of string-rich column to the left, you can use @samp{<r>},
  2016. @samp{<c>}@footnote{Centering does not work inside Emacs, but it does have an
  2017. effect when exporting to HTML.} or @samp{<l>} in a similar fashion. You may
  2018. also combine alignment and field width like this: @samp{<l10>}.
  2019. Lines which only contain these formatting cookies will be removed
  2020. automatically when exporting the document.
  2021. @node Column groups, Orgtbl mode, Column width and alignment, Tables
  2022. @section Column groups
  2023. @cindex grouping columns in tables
  2024. When Org exports tables, it does so by default without vertical
  2025. lines because that is visually more satisfying in general. Occasionally
  2026. however, vertical lines can be useful to structure a table into groups
  2027. of columns, much like horizontal lines can do for groups of rows. In
  2028. order to specify column groups, you can use a special row where the
  2029. first field contains only @samp{/}. The further fields can either
  2030. contain @samp{<} to indicate that this column should start a group,
  2031. @samp{>} to indicate the end of a column, or @samp{<>} (no space between @samp{<}
  2032. and @samp{>}) to make a column
  2033. a group of its own. Boundaries between column groups will upon export be
  2034. marked with vertical lines. Here is an example:
  2035. @example
  2036. | N | N^2 | N^3 | N^4 | sqrt(n) | sqrt[4](N) |
  2037. |---+-----+-----+-----+---------+------------|
  2038. | / | < | | > | < | > |
  2039. | 1 | 1 | 1 | 1 | 1 | 1 |
  2040. | 2 | 4 | 8 | 16 | 1.4142 | 1.1892 |
  2041. | 3 | 9 | 27 | 81 | 1.7321 | 1.3161 |
  2042. |---+-----+-----+-----+---------+------------|
  2043. #+TBLFM: $2=$1^2::$3=$1^3::$4=$1^4::$5=sqrt($1)::$6=sqrt(sqrt(($1)))
  2044. @end example
  2045. It is also sufficient to just insert the column group starters after
  2046. every vertical line you would like to have:
  2047. @example
  2048. | N | N^2 | N^3 | N^4 | sqrt(n) | sqrt[4](N) |

  2056. If you like the intuitive way the Org table editor works, you

  2058. The minor mode Orgtbl mode makes this possible. You can always toggle

  2062. (add-hook 'message-mode-hook 'turn-on-orgtbl)
  2063. @end lisp
  2064. Furthermore, with some special setup, it is possible to maintain tables
  2065. in arbitrary syntax with Orgtbl mode. For example, it is possible to
  2066. construct @LaTeX{} tables with the underlying ease and power of
  2067. Orgtbl mode, including spreadsheet capabilities. For details, see

  2077. is not identical to other spreadsheets. For example, Org knows the concept
  2078. of a @emph{column formula} that will be applied to all non-header fields in a
  2079. column without having to copy the formula to each relevant field. There is
  2080. also a formula debugger, and a formula editor with features for highlighting

  2097. To compute fields in the table from other fields, formulas must
  2098. reference other fields or ranges. In Org, fields can be referenced
  2099. by name, by absolute coordinates, and by relative coordinates. To find
  2100. out what the coordinates of a field are, press @kbd{C-c ?} in that
  2101. field, or press @kbd{C-c @}} to toggle the display of a grid.
  2102. @subsubheading Field references

  2104. @cindex references, to fields
  2105. Formulas can reference the value of another field in two ways. Like in
  2106. any other spreadsheet, you may reference fields with a letter/number
  2107. combination like @code{B3}, meaning the 2nd field in the 3rd row.
  2108. @vindex org-table-use-standard-references
  2109. However, Org prefers@footnote{Org will understand references typed by the
  2110. user as @samp{B4}, but it will not use this syntax when offering a formula
  2111. for editing. You can customize this behavior using the variable
  2112. @code{org-table-use-standard-references}.} to use another, more general
  2113. representation that looks like this:
  2114. @example
  2115. @@@var{row}$@var{column}
  2116. @end example
  2117. Column specifications can be absolute like @code{$1},
  2118. @code{$2},...@code{$@var{N}}, or relative to the current column (i.e.@: the
  2119. column of the field which is being computed) like @code{$+1} or @code{$-2}.
  2120. @code{$<} and @code{$>} are immutable references to the first and last
  2121. column, respectively, and you can use @code{$>>>} to indicate the third
  2122. column from the right.
  2123. The row specification only counts data lines and ignores horizontal separator
  2124. lines (hlines). Like with columns, you can use absolute row numbers
  2125. @code{@@1}, @code{@@2},...@code{@@@var{N}}, and row numbers relative to the
  2126. current row like @code{@@+3} or @code{@@-1}. @code{@@<} and @code{@@>} are
  2127. immutable references the first and last@footnote{For backward compatibility
  2128. you can also use special names like @code{$LR5} and @code{$LR12} to refer in
  2129. a stable way to the 5th and 12th field in the last row of the table.
  2130. However, this syntax is deprecated, it should not be used for new documents.
  2131. Use @code{@@>$} instead.} row in the table, respectively. You may also
  2132. specify the row relative to one of the hlines: @code{@@I} refers to the first
  2133. hline, @code{@@II} to the second, etc@. @code{@@-I} refers to the first such
  2134. line above the current line, @code{@@+I} to the first such line below the
  2135. current line. You can also write @code{@@III+2} which is the second data line
  2136. after the third hline in the table.
  2137. @code{@@0} and @code{$0} refer to the current row and column, respectively,
  2138. i.e. to the row/column for the field being computed. Also, if you omit
  2139. either the column or the row part of the reference, the current row/column is
  2140. implied.
  2141. Org's references with @emph{unsigned} numbers are fixed references
  2142. in the sense that if you use the same reference in the formula for two
  2143. different fields, the same field will be referenced each time.
  2144. Org's references with @emph{signed} numbers are floating
  2145. references because the same reference operator can reference different
  2146. fields depending on the field being calculated by the formula.
  2147. Here are a few examples:
  2148. @example
  2149. @@2$3 @r{2nd row, 3rd column (same as @code{C2})}

  2161. current row, you may simply use @samp{$2..$7}, but if at least one field
  2162. is in a different row, you need to use the general @code{@@row$column}
  2163. format at least for the first field (i.e the reference must start with
  2164. @samp{@@} in order to be interpreted correctly). Examples:
  2165. @example

  2173. @noindent Range references return a vector of values that can be fed

  2175. suppressed, so that the vector contains only the non-empty fields (but

  2269. format, however, has been changed to @code{(float 8)} to keep tables
  2270. compact. The default settings can be configured using the variable
  2271. @code{org-calc-default-modes}.
  2272. @example
  2273. p20 @r{set the internal Calc calculation precision to 20 digits}
  2274. n3 s3 e2 f4 @r{Normal, scientific, engineering, or fixed}
  2275. @r{format of the result of Calc passed back to Org.}
  2276. @r{Calc formatting is unlimited in precision as}
  2277. @r{long as the Calc calculation precision is greater.}
  2278. D R @r{angle modes: degrees, radians}
  2279. F S @r{fraction and symbolic modes}
  2280. N @r{interpret all fields as numbers, use 0 for non-numbers}
  2281. E @r{keep empty fields in ranges}
  2282. L @r{literal}
  2283. @end example
  2284. @noindent
  2285. Unless you use large integer numbers or high-precision-calculation
  2286. and -display for floating point numbers you may alternatively provide a
  2287. @code{printf} format specifier to reformat the Calc result after it has been
  2288. passed back to Org instead of letting Calc already do the
  2289. formatting@footnote{The @code{printf} reformatting is limited in precision
  2290. because the value passed to it is converted into an @code{integer} or
  2291. @code{double}. The @code{integer} is limited in size by truncating the
  2292. signed value to 32 bits. The @code{double} is limited in precision to 64
  2293. bits overall which leaves approximately 16 significant decimal digits.}.
  2294. A few examples:
  2295. @example
  2296. $1+$2 @r{Sum of first and second field}
  2297. $1+$2;%.2f @r{Same, format result to two decimals}
  2298. exp($2)+exp($1) @r{Math functions can be used}
  2299. $0;%.1f @r{Reformat current cell to 1 decimal}
  2300. ($3-32)*5/9 @r{Degrees F -> C conversion}
  2301. $c/$1/$cm @r{Hz -> cm conversion, using @file{constants.el}}
  2302. tan($1);Dp3s1 @r{Compute in degrees, precision 3, display SCI 1}
  2303. sin($1);Dp3%.1e @r{Same, but use printf specifier for display}
  2304. vmean($2..$7) @r{Compute column range mean, using vector function}
  2305. vmean($2..$7);EN @r{Same, but treat empty fields as 0}
  2306. taylor($3,x=7,2) @r{Taylor series of $3, at x=7, second degree}
  2307. @end example
  2308. Calc also contains a complete set of logical operations. For example
  2309. @example
  2310. if($1<20,teen,string("")) @r{"teen" if age $1 less than 20, else empty}
  2311. @end example
  2312. Note that you can also use two org-specific flags @code{T} and @code{t} for
  2313. durations computations @ref{Durations and time values}.

  2315. @subsection Emacs Lisp forms as formulas
  2316. @cindex Lisp forms, as table formulas
  2317. It is also possible to write a formula in Emacs Lisp. This can be useful
  2318. for string manipulation and control structures, if Calc's functionality is
  2319. not enough.
  2320. If a formula starts with a single-quote followed by an opening parenthesis,
  2321. then it is evaluated as a Lisp form. The evaluation should return either a
  2322. string or a number. Just as with @file{calc} formulas, you can specify modes
  2323. and a printf format after a semicolon.
  2324. With Emacs Lisp forms, you need to be conscious about the way field
  2325. references are interpolated into the form. By default, a reference will be
  2326. interpolated as a Lisp string (in double-quotes) containing the field. If
  2327. you provide the @samp{N} mode switch, all referenced elements will be numbers
  2328. (non-number fields will be zero) and interpolated as Lisp numbers, without
  2329. quotes. If you provide the @samp{L} flag, all fields will be interpolated
  2330. literally, without quotes. I.e., if you want a reference to be interpreted
  2331. as a string by the Lisp form, enclose the reference operator itself in
  2332. double-quotes, like @code{"$3"}. Ranges are inserted as space-separated
  2333. fields, so you can embed them in list or vector syntax.
  2334. Here are a few examples---note how the @samp{N} mode is used when we do
  2335. computations in Lisp:
  2336. @example
  2337. @r{Swap the first two characters of the content of column 1}
  2338. '(concat (substring $1 1 2) (substring $1 0 1) (substring $1 2))
  2339. @r{Add columns 1 and 2, equivalent to Calc's @code{$1+$2}}
  2340. '(+ $1 $2);N
  2341. @r{Compute the sum of columns 1-4, like Calc's @code{vsum($1..$4)}}
  2342. '(apply '+ '($1..$4));N

  2360. Input duration values must be of the form @code{[HH:MM[:SS]}, where seconds
  2361. are optional. With the @code{T} flag, computed durations will be displayed
  2362. as @code{HH:MM:SS} (see the first formula above). With the @code{t} flag,
  2363. computed durations will be displayed according to the value of the variable
  2364. @code{org-table-duration-custom-format}, which defaults to @code{'hours} and
  2365. will display the result as a fraction of hours (see the second formula in the
  2366. example above).
  2367. Negative duration values can be manipulated as well, and integers will be
  2368. considered as seconds in addition and subtraction.

  2377. @key{TAB} or @key{RET} or @kbd{C-c C-c} with the cursor still in the field,
  2378. the formula will be stored as the formula for this field, evaluated, and the
  2379. current field will be replaced with the result.
  2380. @cindex #+TBLFM
  2381. Formulas are stored in a special line starting with @samp{#+TBLFM:} directly
  2382. below the table. If you type the equation in the 4th field of the 3rd data
  2383. line in the table, the formula will look like @samp{@@3$4=$1+$2}. When
  2384. inserting/deleting/swapping column and rows with the appropriate commands,
  2385. @i{absolute references} (but not relative ones) in stored formulas are
  2386. modified in order to still reference the same field. To avoid this from
  2387. happening, in particular in range references, anchor ranges at the table
  2388. borders (using @code{@@<}, @code{@@>}, @code{$<}, @code{$>}), or at hlines
  2389. using the @code{@@I} notation. Automatic adaptation of field references does
  2390. of course not happen if you edit the table structure with normal editing
  2391. commands---then you must fix the equations yourself.
  2392. Instead of typing an equation into the field, you may also use the following
  2393. command
  2394. @table @kbd
  2395. @orgcmd{C-u C-c =,org-table-eval-formula}
  2396. Install a new formula for the current field. The command prompts for a

  2398. it to the current field, and stores it.

  2424. very convenient exceptions: (i) If the table contains horizontal separator
  2425. hlines, everything before the first such line is considered part of the table
  2426. @emph{header} and will not be modified by column formulas. (ii) Fields that
  2427. already get a value from a field/range formula will be left alone by column
  2428. formulas. These conditions make column formulas very easy to use.
  2429. To assign a formula to a column, type it directly into any field in the
  2430. column, preceded by an equal sign, like @samp{=$1+$2}. When you press
  2431. @key{TAB} or @key{RET} or @kbd{C-c C-c} with the cursor still in the field,
  2432. the formula will be stored as the formula for the current column, evaluated
  2433. and the current field replaced with the result. If the field contains only
  2434. @samp{=}, the previously stored formula for this column is used. For each
  2435. column, Org will only remember the most recently used formula. In the
  2436. @samp{#+TBLFM:} line, column formulas will look like @samp{$4=$1+$2}. The

  2443. Install a new formula for the current column and replace current field with

  2632. Similar to @samp{^}, but defines names for the fields in the row
  2633. @emph{below}.
  2634. @item $
  2635. Fields in this row can define @emph{parameters} for formulas. For
  2636. example, if a field in a @samp{$} row contains @samp{max=50}, then
  2637. formulas in this table can refer to the value 50 using @samp{$max}.
  2638. Parameters work exactly like constants, only that they can be defined on
  2639. a per-table basis.
  2640. @item #
  2641. Fields in this row are automatically recalculated when pressing
  2642. @key{TAB} or @key{RET} or @kbd{S-@key{TAB}} in this row. Also, this row
  2643. is selected for a global recalculation with @kbd{C-u C-c *}. Unmarked
  2644. lines will be left alone by this command.
  2645. @item *
  2646. Selects this line for global recalculation with @kbd{C-u C-c *}, but
  2647. not for automatic recalculation. Use this when automatic
  2648. recalculation slows down editing too much.
  2649. @item
  2650. Unmarked lines are exempt from recalculation with @kbd{C-u C-c *}.
  2651. All lines that should be recalculated should be marked with @samp{#}
  2652. or @samp{*}.
  2653. @item /
  2654. Do not export this line. Useful for lines that contain the narrowing
  2655. @samp{<N>} markers or column group markers.

  2763. Org will recognize plain URL-like links and activate them as
  2764. clickable links. The general link format, however, looks like this:
  2765. @example
  2766. [[link][description]] @r{or alternatively} [[link]]
  2767. @end example
  2768. @noindent
  2769. Once a link in the buffer is complete (all brackets present), Org
  2770. will change the display so that @samp{description} is displayed instead
  2771. of @samp{[[link][description]]} and @samp{link} is displayed instead of
  2772. @samp{[[link]]}. Links will be highlighted in the face @code{org-link},
  2773. which by default is an underlined face. You can directly edit the
  2774. visible part of a link. Note that this can be either the @samp{link}
  2775. part (if there is no description) or the @samp{description} part. To
  2776. edit also the invisible @samp{link} part, use @kbd{C-c C-l} with the
  2777. cursor on the link.
  2778. If you place the cursor at the beginning or just behind the end of the
  2779. displayed text and press @key{BACKSPACE}, you will remove the
  2780. (invisible) bracket at that location. This makes the link incomplete
  2781. and the internals are again displayed as plain text. Inserting the
  2782. missing bracket hides the link internals again. To show the
  2783. internal structure of all links, use the menu entry

  2791. If the link does not look like a URL, it is considered to be internal in the
  2792. current file. The most important case is a link like
  2793. @samp{[[#my-custom-id]]} which will link to the entry with the
  2794. @code{CUSTOM_ID} property @samp{my-custom-id}. Such custom IDs are very good
  2795. for HTML export (@pxref{HTML export}) where they produce pretty section
  2796. links. You are responsible yourself to make sure these custom IDs are unique
  2797. in a file.
  2798. Links such as @samp{[[My Target]]} or @samp{[[My Target][Find my target]]}
  2799. lead to a text search in the current file.
  2800. The link can be followed with @kbd{C-c C-o} when the cursor is on the link,
  2801. or with a mouse click (@pxref{Handling links}). Links to custom IDs will
  2802. point to the corresponding headline. The preferred match for a text link is
  2803. a @i{dedicated target}: the same string in double angular brackets. Targets
  2804. may be located anywhere; sometimes it is convenient to put them into a
  2805. comment line. For example
  2806. @example
  2807. # <<My Target>>
  2808. @end example
  2809. @noindent In HTML export (@pxref{HTML export}), such targets will become
  2810. named anchors for direct access through @samp{http} links@footnote{Note that
  2811. text before the first headline is usually not exported, so the first such
  2812. target should be after the first headline, or in the line directly before the
  2813. first headline.}.
  2814. If no dedicated target exists, Org will search for a headline that is exactly
  2815. the link text but may also include a TODO keyword and tags@footnote{To insert
  2816. a link targeting a headline, in-buffer completion can be used. Just type a
  2817. star followed by a few optional letters into the buffer and press
  2818. @kbd{M-@key{TAB}}. All headlines in the current buffer will be offered as
  2819. completions.}. In non-Org files, the search will look for the words in the
  2820. link text. In the above example the search would be for @samp{my target}.
  2821. Following a link pushes a mark onto Org's own mark ring. You can
  2822. return to the previous position with @kbd{C-c &}. Using this command
  2823. several times in direct succession goes back to positions recorded
  2824. earlier.

  2833. Org can automatically turn any occurrences of certain target names
  2834. in normal text into a link. So without explicitly creating a link, the
  2835. text connects to the target radioing its position. Radio targets are
  2836. enclosed by triple angular brackets. For example, a target @samp{<<<My
  2837. Target>>>} causes each occurrence of @samp{my target} in normal text to
  2838. become activated as a link. The Org file is scanned automatically
  2839. for radio targets only when the file is first loaded into Emacs. To
  2840. update the target list during editing, press @kbd{C-c C-c} with the
  2841. cursor on or at a target.

  2911. A link should be enclosed in double brackets and may contain a
  2912. descriptive text to be displayed instead of the URL (@pxref{Link
  2913. format}), for example:
  2914. @example
  2915. [[http://www.gnu.org/software/emacs/][GNU Emacs]]
  2916. @end example
  2917. @noindent
  2918. If the description is a file name or URL that points to an image, HTML
  2919. export (@pxref{HTML export}) will inline the image as a clickable
  2920. button. If there is no description at all and the link points to an
  2921. image,
  2922. that image will be inlined into the exported HTML file.
  2923. @cindex square brackets, around links
  2924. @cindex plain text external links
  2925. Org also finds external links in the normal text and activates them
  2926. as links. If spaces must be part of the link (for example in
  2927. @samp{bbdb:Richard Stallman}), or if you need to remove ambiguities
  2928. about the end of the link, enclose them in square brackets.

  2931. @cindex links, handling
  2932. Org provides methods to create a link in the correct syntax, to
  2933. insert it into an Org file, and to follow the link.
  2934. @table @kbd
  2935. @orgcmd{C-c l,org-store-link}
  2936. @cindex storing links
  2937. Store a link to the current location. This is a @emph{global} command (you
  2938. must create the key binding yourself) which can be used in any buffer to
  2939. create a link. The link will be stored for later insertion into an Org
  2940. buffer (see below). What kind of link will be created depends on the current
  2941. buffer:
  2942. @b{Org mode buffers}@*
  2943. For Org files, if there is a @samp{<<target>>} at the cursor, the link points
  2944. to the target. Otherwise it points to the current headline, which will also
  2945. be the description@footnote{If the headline contains a timestamp, it will be
  2946. removed from the link and result in a wrong link -- you should avoid putting
  2947. timestamp in the headline.}.
  2948. @vindex org-link-to-org-use-id
  2949. @cindex property, CUSTOM_ID
  2950. @cindex property, ID
  2951. If the headline has a @code{CUSTOM_ID} property, a link to this custom ID
  2952. will be stored. In addition or alternatively (depending on the value of
  2953. @code{org-link-to-org-use-id}), a globally unique @code{ID} property will be
  2954. created and/or used to construct a link. So using this command in Org
  2955. buffers will potentially create two links: a human-readable from the custom
  2956. ID, and one that is globally unique and works even if the entry is moved from
  2957. file to file. Later, when inserting the link, you need to decide which one
  2958. to use.
  2959. @b{Email/News clients: VM, Rmail, Wanderlust, MH-E, Gnus}@*
  2960. Pretty much all Emacs mail clients are supported. The link will point to the
  2961. current article, or, in some GNUS buffers, to the group. The description is
  2962. constructed from the author and the subject.
  2963. @b{Web browsers: W3 and W3M}@*
  2964. Here the link will be the current URL, with the page title as description.
  2965. @b{Contacts: BBDB}@*
  2966. Links created in a BBDB buffer will point to the current entry.
  2967. @b{Chat: IRC}@*
  2968. @vindex org-irc-link-to-logs
  2969. For IRC links, if you set the variable @code{org-irc-link-to-logs} to
  2970. @code{t}, a @samp{file:/} style link to the relevant point in the logs for
  2971. the current conversation is created. Otherwise an @samp{irc:/} style link to
  2972. the user/channel/server under the point will be stored.
  2973. @b{Other files}@*
  2974. For any other files, the link will point to the file, with a search string
  2975. (@pxref{Search options}) pointing to the contents of the current line. If
  2976. there is an active region, the selected words will form the basis of the
  2977. search string. If the automatically created link is not working correctly or
  2978. accurately enough, you can write custom functions to select the search string
  2979. and to do the search for particular file types---see @ref{Custom searches}.
  2980. The key binding @kbd{C-c l} is only a suggestion---see @ref{Installation}.
  2981. @b{Agenda view}@*
  2982. When the cursor is in an agenda view, the created link points to the
  2983. entry referenced by the current line.
  2984. @c
  2985. @orgcmd{C-c C-l,org-insert-link}
  2986. @cindex link completion
  2987. @cindex completion, of links
  2988. @cindex inserting links
  2989. @vindex org-keep-stored-link-after-insertion
  2990. Insert a link@footnote{ Note that you don't have to use this command to
  2991. insert a link. Links in Org are plain text, and you can type or paste them
  2992. straight into the buffer. By using this command, the links are automatically
  2993. enclosed in double brackets, and you will be asked for the optional
  2994. descriptive text.}. This prompts for a link to be inserted into the buffer.
  2995. You can just type a link, using text for an internal link, or one of the link
  2996. type prefixes mentioned in the examples above. The link will be inserted
  2997. into the buffer@footnote{After insertion of a stored link, the link will be
  2998. removed from the list of stored links. To keep it in the list later use, use
  2999. a triple @kbd{C-u} prefix argument to @kbd{C-c C-l}, or configure the option
  3000. @code{org-keep-stored-link-after-insertion}.}, along with a descriptive text.
  3001. If some text was selected when this command is called, the selected text
  3002. becomes the default description.
  3003. @b{Inserting stored links}@*
  3004. All links stored during the

  3006. them with @key{up} and @key{down} (or @kbd{M-p/n}).
  3007. @b{Completion support}@* Completion with @key{TAB} will help you to insert
  3008. valid link prefixes like @samp{http:} or @samp{ftp:}, including the prefixes
  3009. defined through link abbreviations (@pxref{Link abbreviations}). If you
  3010. press @key{RET} after inserting only the @var{prefix}, Org will offer
  3011. specific completion support for some link types@footnote{This works by
  3012. calling a special function @code{org-PREFIX-complete-link}.} For
  3013. example, if you type @kbd{file @key{RET}}, file name completion (alternative
  3014. access: @kbd{C-u C-c C-l}, see below) will be offered, and after @kbd{bbdb
  3015. @key{RET}} you can complete contact names.

  3017. @cindex file name completion
  3018. @cindex completion, of file names
  3019. When @kbd{C-c C-l} is called with a @kbd{C-u} prefix argument, a link to
  3020. a file will be inserted and you may use file name completion to select
  3021. the name of the file. The path to the file is inserted relative to the
  3022. directory of the current Org file, if the linked file is in the current
  3023. directory or in a sub-directory of it, or if the path is written relative
  3024. to the current directory using @samp{../}. Otherwise an absolute path
  3025. is used, if possible with @samp{~/} for your home directory. You can
  3026. force an absolute path with two @kbd{C-u} prefixes.
  3027. @c
  3028. @item C-c C-l @ @r{(with cursor on existing link)}
  3029. When the cursor is on an existing link, @kbd{C-c C-l} allows you to edit the

  3036. Open link at point. This will launch a web browser for URLs (using
  3037. @command{browse-url-at-point}), run VM/MH-E/Wanderlust/Rmail/Gnus/BBDB for
  3038. the corresponding links, and execute the command in a shell link. When the
  3039. cursor is on an internal link, this command runs the corresponding search.
  3040. When the cursor is on a TAG list in a headline, it creates the corresponding
  3041. TAGS view. If the cursor is on a timestamp, it compiles the agenda for that
  3042. date. Furthermore, it will visit text and remote files in @samp{file:} links
  3043. with Emacs and select a suitable application for local non-text files.
  3044. Classification of files is based on file extension only. See option
  3045. @code{org-file-apps}. If you want to override the default application and
  3046. visit the file with Emacs, use a @kbd{C-u} prefix. If you want to avoid
  3047. opening in Emacs, use a @kbd{C-u C-u} prefix.@*
  3048. If the cursor is on a headline, but not on a link, offer all links in the
  3049. headline and entry text. If you want to setup the frame configuration for
  3050. following links, customize @code{org-link-frame-setup}.

  3077. images that have no description part in the link, i.e.@: images that will also
  3078. be inlined during export. When called with a prefix argument, also display
  3079. images that do have a link description. You can ask for inline images to be
  3080. displayed at startup by configuring the variable

  3110. You can insert and follow links that have Org syntax not only in
  3111. Org, but in any Emacs buffer. For this, you should create two
  3112. global commands, like this (please select suitable global keys
  3113. yourself):
  3114. @lisp
  3115. (global-set-key "\C-c L" 'org-insert-link-global)

  3121. @cindex abbreviation, links
  3122. Long URLs can be cumbersome to type, and often many similar links are
  3123. needed in a document. For this you can use link abbreviations. An
  3124. abbreviated link looks like this
  3125. @example
  3126. [[linkword:tag][description]]
  3127. @end example
  3128. @noindent
  3129. @vindex org-link-abbrev-alist
  3130. where the tag is optional.
  3131. The @i{linkword} must be a word, starting with a letter, followed by
  3132. letters, numbers, @samp{-}, and @samp{_}. Abbreviations are resolved
  3133. according to the information in the variable @code{org-link-abbrev-alist}
  3134. that relates the linkwords to replacement text. Here is an example:
  3135. @smalllisp
  3136. @group
  3137. (setq org-link-abbrev-alist
  3138. '(("bugzilla" . "http://10.1.2.9/bugzilla/show_bug.cgi?id=")
  3139. ("url-to-ja" . "http://translate.google.fr/translate?sl=en&tl=ja&u=%h")

  3143. ("ads" . "http://adsabs.harvard.edu/cgi-bin/nph-abs_connect?author=%s&db_key=AST")))
  3144. @end group
  3145. @end smalllisp
  3146. If the replacement text contains the string @samp{%s}, it will be
  3147. replaced with the tag. Using @samp{%h} instead of @samp{%s} will
  3148. url-encode the tag (see the example above, where we need to encode
  3149. the URL parameter.) Using @samp{%(my-function)} will pass the tag
  3150. to a custom function, and replace it by the resulting string.
  3151. If the replacement text don't contain any specifier, it will simply
  3152. be appended to the string in order to create the link.
  3153. Instead of a string, you may also specify a function that will be
  3154. called with the tag as the only argument to create the link.
  3155. With the above setting, you could link to a specific bug with
  3156. @code{[[bugzilla:129]]}, search the web for @samp{OrgMode} with
  3157. @code{[[google:OrgMode]]}, show the map location of the Free Software
  3158. Foundation @code{[[gmap:51 Franklin Street, Boston]]} or of Carsten office
  3159. @code{[[omap:Science Park 904, Amsterdam, The Netherlands]]} and find out
  3160. what the Org author is doing besides Emacs hacking with
  3161. @code{[[ads:Dominik,C]]}.
  3162. If you need special abbreviations just for a single Org buffer, you
  3163. can define them in the file with
  3164. @cindex #+LINK
  3165. @example
  3166. #+LINK: bugzilla http://10.1.2.9/bugzilla/show_bug.cgi?id=
  3167. #+LINK: google http://www.google.com/search?q=%s
  3168. @end example
  3169. @noindent
  3170. In-buffer completion (@pxref{Completion}) can be used after @samp{[} to
  3171. complete link abbreviations. You may also define a function
  3172. @code{org-PREFIX-complete-link} that implements special (e.g.@: completion)
  3173. support for inserting such a link with @kbd{C-c C-l}. Such a function should
  3174. not accept any arguments, and return the full link with prefix.

  3179. File links can contain additional information to make Emacs jump to a
  3180. particular location in the file when following a link. This can be a
  3181. line number or a search option after a double@footnote{For backward
  3182. compatibility, line numbers can also follow a single colon.} colon. For
  3183. example, when the command @kbd{C-c l} creates a link (@pxref{Handling
  3184. links}) to a file, it encodes the words in the current line as a search
  3185. string that can be used to find this line back later when following the
  3186. link with @kbd{C-c C-o}.
  3187. Here is the syntax of the different ways to attach a search to a file
  3188. link, together with an explanation:
  3189. @example
  3190. [[file:~/code/main.c::255]]
  3191. [[file:~/xx.org::My Target]]
  3192. [[file:~/xx.org::*My Target]]
  3193. [[file:~/xx.org::#my-custom-id]]
  3194. [[file:~/xx.org::/regexp/]]
  3195. @end example
  3196. @table @code
  3197. @item 255
  3198. Jump to line 255.
  3199. @item My Target
  3200. Search for a link target @samp{<<My Target>>}, or do a text search for
  3201. @samp{my target}, similar to the search in internal links, see
  3202. @ref{Internal links}. In HTML export (@pxref{HTML export}), such a file
  3203. link will become a HTML reference to the corresponding named anchor in
  3204. the linked file.
  3205. @item *My Target
  3206. In an Org file, restrict search to headlines.
  3207. @item #my-custom-id
  3208. Link to a heading with a @code{CUSTOM_ID} property
  3209. @item /regexp/
  3210. Do a regular expression search for @code{regexp}. This uses the Emacs
  3211. command @code{occur} to list all matches in a separate window. If the
  3212. target file is in Org mode, @code{org-occur} is used to create a
  3213. sparse tree with the matches.
  3214. @c If the target file is a directory,
  3215. @c @code{grep} will be used to search all files in the directory.
  3216. @end table
  3217. As a degenerate case, a file link with an empty file name can be used
  3218. to search the current file. For example, @code{[[file:::find me]]} does
  3219. a search for @samp{find me} in the current file, just as
  3220. @samp{[[find me]]} would.

  3225. The default mechanism for creating search strings and for doing the
  3226. actual search related to a file link may not work correctly in all
  3227. cases. For example, Bib@TeX{} database files have many entries like
  3228. @samp{year="1993"} which would not result in good search strings,
  3229. because the only unique identification for a Bib@TeX{} entry is the
  3230. citation key.
  3231. @vindex org-create-file-search-functions
  3232. @vindex org-execute-file-search-functions
  3233. If you come across such a problem, you can write custom functions to set
  3234. the right search string for a particular file type, and to do the search
  3235. for the string in the file. Using @code{add-hook}, these functions need
  3236. to be added to the hook variables
  3237. @code{org-create-file-search-functions} and
  3238. @code{org-execute-file-search-functions}. See the docstring for these
  3239. variables for more information. Org actually uses this mechanism
  3240. for Bib@TeX{} database files, and you can use the corresponding code as
  3241. an implementation example. See the file @file{org-bibtex.el}.

  3245. Org mode does not maintain TODO lists as separate documents@footnote{Of
  3246. course, you can make a document that contains only long lists of TODO items,
  3247. but this is not required.}. Instead, TODO items are an integral part of the
  3248. notes file, because TODO items usually come up while taking notes! With Org
  3249. mode, simply mark any entry in a tree as being a TODO item. In this way,
  3250. information is not duplicated, and the entire context from which the TODO
  3251. item emerged is always present.
  3252. Of course, this technique for managing TODO items scatters them
  3253. throughout your notes file. Org mode compensates for this by providing
  3254. methods to give you an overview of all the things that you have to do.

  3345. You can use TODO keywords to indicate different @emph{sequential} states
  3346. in the process of working on an item, for example@footnote{Changing
  3347. this variable only becomes effective after restarting Org mode in a
  3348. buffer.}:
  3349. @lisp
  3350. (setq org-todo-keywords
  3351. '((sequence "TODO" "FEEDBACK" "VERIFY" "|" "DONE" "DELEGATED")))
  3352. @end lisp
  3353. The vertical bar separates the TODO keywords (states that @emph{need
  3354. action}) from the DONE states (which need @emph{no further action}). If
  3355. you don't provide the separator bar, the last state is used as the DONE
  3356. state.
  3357. @cindex completion, of TODO keywords
  3358. With this setup, the command @kbd{C-c C-t} will cycle an entry from TODO
  3359. to FEEDBACK, then to VERIFY, and finally to DONE and DELEGATED. You may
  3360. also use a numeric prefix argument to quickly select a specific state. For
  3361. example @kbd{C-3 C-c C-t} will change the state immediately to VERIFY.
  3362. Or you can use @kbd{S-@key{left}} to go backward through the sequence. If you
  3363. define many keywords, you can use in-buffer completion
  3364. (@pxref{Completion}) or even a special one-key selection scheme
  3365. (@pxref{Fast access to TODO states}) to insert these words into the
  3366. buffer. Changing a TODO state can be logged with a timestamp, see
  3367. @ref{Tracking TODO state changes}, for more information.
  3368. @node TODO types, Multiple sets in one file, Workflow states, TODO extensions

  3370. @cindex TODO types
  3371. @cindex names as TODO keywords
  3372. @cindex types as TODO keywords
  3373. The second possibility is to use TODO keywords to indicate different
  3374. @emph{types} of action items. For example, you might want to indicate
  3375. that items are for ``work'' or ``home''. Or, when you work with several
  3376. people on a single project, you might want to assign action items
  3377. directly to persons, by using their names as TODO keywords. This would
  3378. be set up like this:
  3379. @lisp
  3380. (setq org-todo-keywords '((type "Fred" "Sara" "Lucy" "|" "DONE")))
  3381. @end lisp
  3382. In this case, different keywords do not indicate a sequence, but rather
  3383. different types. So the normal work flow would be to assign a task to a
  3384. person, and later to mark it DONE. Org mode supports this style by adapting
  3385. the workings of the command @kbd{C-c C-t}@footnote{This is also true for the
  3386. @kbd{t} command in the timeline and agenda buffers.}. When used several
  3387. times in succession, it will still cycle through all names, in order to first
  3388. select the right type for a task. But when you return to the item after some
  3389. time and execute @kbd{C-c C-t} again, it will switch from any name directly
  3390. to DONE. Use prefix arguments or completion to quickly select a specific
  3391. name. You can also review the items of a specific TODO type in a sparse tree
  3392. by using a numeric prefix to @kbd{C-c / t}. For example, to see all things
  3393. Lucy has to do, you would use @kbd{C-3 C-c / t}. To collect Lucy's items
  3394. from all agenda files into a single buffer, you would use the numeric prefix
  3395. argument as well when creating the global TODO list: @kbd{C-3 C-c a t}.

  3397. @subsection Multiple keyword sets in one file
  3398. @cindex TODO keyword sets
  3399. Sometimes you may want to use different sets of TODO keywords in
  3400. parallel. For example, you may want to have the basic
  3401. @code{TODO}/@code{DONE}, but also a workflow for bug fixing, and a
  3402. separate state indicating that an item has been canceled (so it is not
  3403. DONE, but also does not require action). Your setup would then look
  3404. like this:
  3405. @lisp
  3406. (setq org-todo-keywords
  3407. '((sequence "TODO" "|" "DONE")
  3408. (sequence "REPORT" "BUG" "KNOWNCAUSE" "|" "FIXED")
  3409. (sequence "|" "CANCELED")))
  3410. @end lisp
  3411. The keywords should all be different, this helps Org mode to keep track
  3412. of which subsequence should be used for a given entry. In this setup,
  3413. @kbd{C-c C-t} only operates within a subsequence, so it switches from
  3414. @code{DONE} to (nothing) to @code{TODO}, and from @code{FIXED} to
  3415. (nothing) to @code{REPORT}. Therefore you need a mechanism to initially
  3416. select the correct sequence. Besides the obvious ways like typing a
  3417. keyword or using completion, you may also apply the following commands:
  3418. @table @kbd
  3419. @kindex C-S-@key{right}
  3420. @kindex C-S-@key{left}
  3421. @kindex C-u C-u C-c C-t
  3422. @item C-u C-u C-c C-t
  3423. @itemx C-S-@key{right}
  3424. @itemx C-S-@key{left}
  3425. These keys jump from one TODO subset to the next. In the above example,
  3426. @kbd{C-u C-u C-c C-t} or @kbd{C-S-@key{right}} would jump from @code{TODO} or
  3427. @code{DONE} to @code{REPORT}, and any of the words in the second row to
  3428. @code{CANCELED}. Note that the @kbd{C-S-} key binding conflict with
  3429. @code{shift-selection-mode} (@pxref{Conflicts}).
  3430. @kindex S-@key{right}
  3431. @kindex S-@key{left}
  3432. @item S-@key{right}
  3433. @itemx S-@key{left}
  3434. @kbd{S-@key{<left>}} and @kbd{S-@key{<right>}} and walk through @emph{all}
  3435. keywords from all sets, so for example @kbd{S-@key{<right>}} would switch
  3436. from @code{DONE} to @code{REPORT} in the example above. See also
  3437. @ref{Conflicts}, for a discussion of the interaction with
  3438. @code{shift-selection-mode}.

  3441. @subsection Fast access to TODO states
  3442. If you would like to quickly change an entry to an arbitrary TODO state
  3443. instead of cycling through the states, you can set up keys for single-letter
  3444. access to the states. This is done by adding the selection character after
  3445. each keyword, in parentheses@footnote{All characters are allowed except
  3446. @code{@@^!}, which have a special meaning here.}. For example:
  3447. @lisp
  3448. (setq org-todo-keywords
  3449. '((sequence "TODO(t)" "|" "DONE(d)")
  3450. (sequence "REPORT(r)" "BUG(b)" "KNOWNCAUSE(k)" "|" "FIXED(f)")

  3454. If you then press @kbd{C-c C-t} followed by the selection key, the entry
  3455. will be switched to this state. @kbd{SPC} can be used to remove any TODO
  3456. keyword from an entry.@footnote{Check also the variable
  3457. @code{org-fast-tag-selection-include-todo}, it allows you to change the TODO
  3458. state through the tags interface (@pxref{Setting tags}), in case you like to
  3459. mingle the two concepts. Note that this means you need to come up with
  3460. unique keys across both sets of keywords.}

  3468. It can be very useful to use different aspects of the TODO mechanism in
  3469. different files. For file-local settings, you need to add special lines
  3470. to the file which set the keywords and interpretation for that file
  3471. only. For example, to set one of the two examples discussed above, you
  3472. need one of the following lines, starting in column zero anywhere in the
  3473. file:
  3474. @example
  3475. #+TODO: TODO FEEDBACK VERIFY | DONE CANCELED
  3476. @end example
  3477. @noindent (you may also write @code{#+SEQ_TODO} to be explicit about the
  3478. interpretation, but it means the same as @code{#+TODO}), or
  3479. @example
  3480. #+TYP_TODO: Fred Sara Lucy Mike | DONE
  3481. @end example
  3482. A setup for using several sets in parallel would be:
  3483. @example
  3484. #+TODO: TODO | DONE
  3485. #+TODO: REPORT BUG KNOWNCAUSE | FIXED
  3486. #+TODO: | CANCELED
  3487. @end example
  3488. @cindex completion, of option keywords
  3489. @kindex M-@key{TAB}
  3490. @noindent To make sure you are using the correct keyword, type
  3491. @samp{#+} into the buffer and then use @kbd{M-@key{TAB}} completion.
  3492. @cindex DONE, final TODO keyword
  3493. Remember that the keywords after the vertical bar (or the last keyword
  3494. if no bar is there) must always mean that the item is DONE (although you
  3495. may use a different word). After changing one of these lines, use
  3496. @kbd{C-c C-c} with the cursor still in the line to make the changes
  3497. known to Org mode@footnote{Org mode parses these lines only when
  3498. Org mode is activated after visiting a file. @kbd{C-c C-c} with the
  3499. cursor in a line starting with @samp{#+} is simply restarting Org mode
  3500. for the current buffer.}.

  3507. Org mode highlights TODO keywords with special faces: @code{org-todo}
  3508. for keywords indicating that an item still has to be acted upon, and
  3509. @code{org-done} for keywords indicating that an item is finished. If
  3510. you are using more than 2 different states, you might want to use
  3511. special faces for some of them. This can be done using the variable
  3512. @code{org-todo-keyword-faces}. For example:
  3513. @lisp
  3514. @group
  3515. (setq org-todo-keyword-faces
  3516. '(("TODO" . org-warning) ("STARTED" . "yellow")
  3517. ("CANCELED" . (:foreground "blue" :weight bold))))
  3518. @end group
  3519. @end lisp
  3520. While using a list with face properties as shown for CANCELED @emph{should}
  3521. work, this does not always seem to be the case. If necessary, define a
  3522. special face and use that. A string is interpreted as a color. The variable

  3531. The structure of Org files (hierarchy and lists) makes it easy to define TODO
  3532. dependencies. Usually, a parent TODO task should not be marked DONE until
  3533. all subtasks (defined as children tasks) are marked as DONE. And sometimes
  3534. there is a logical sequence to a number of (sub)tasks, so that one task
  3535. cannot be acted upon before all siblings above it are done. If you customize
  3536. the variable @code{org-enforce-todo-dependencies}, Org will block entries
  3537. from changing state to DONE while they have children that are not DONE.
  3538. Furthermore, if an entry has a property @code{ORDERED}, each of its children
  3539. will be blocked until all earlier siblings are marked DONE. Here is an
  3540. example:
  3541. @example
  3542. * TODO Blocked until (two) is done
  3543. ** DONE one
  3544. ** TODO two

  3556. @cindex property, ORDERED
  3557. Toggle the @code{ORDERED} property of the current entry. A property is used
  3558. for this behavior because this should be local to the current entry, not
  3559. inherited like a tag. However, if you would like to @i{track} the value of
  3560. this property with a tag for better visibility, customize the variable
  3561. @code{org-track-ordered-property-with-tag}.

  3566. If you set the variable @code{org-agenda-dim-blocked-tasks}, TODO entries

  3599. @lisp
  3600. (setq org-log-done 'time)
  3601. @end lisp
  3602. @noindent
  3603. Then each time you turn an entry from a TODO (not-done) state into any
  3604. of the DONE states, a line @samp{CLOSED: [timestamp]} will be inserted
  3605. just after the headline. If you turn the entry back into a TODO item
  3606. through further state cycling, that line will be removed again. If you
  3607. want to record a note along with the timestamp, use@footnote{The
  3608. corresponding in-buffer setting is: @code{#+STARTUP: lognotedone}}
  3609. @lisp
  3610. (setq org-log-done 'note)

  3613. You will then be prompted for a note, and that note will be stored below

  3615. In the timeline (@pxref{Timeline}) and in the agenda
  3616. (@pxref{Weekly/daily agenda}), you can then use the @kbd{l} key to

  3625. When TODO keywords are used as workflow states (@pxref{Workflow states}), you
  3626. might want to keep track of when a state change occurred and maybe take a
  3627. note about this change. You can either record just a timestamp, or a
  3628. time-stamped note for a change. These records will be inserted after the
  3629. headline as an itemized list, newest first@footnote{See the variable
  3630. @code{org-log-states-order-reversed}}. When taking a lot of notes, you might
  3631. want to get the notes out of the way into a drawer (@pxref{Drawers}).
  3632. Customize the variable @code{org-log-into-drawer} to get this behavior---the
  3633. recommended drawer for this is called @code{LOGBOOK}@footnote{Note that the
  3634. @code{LOGBOOK} drawer is unfolded when pressing @key{SPC} in the agenda to
  3635. show an entry---use @key{C-u SPC} to keep it folded here}. You can also
  3636. overrule the setting of this variable for a subtree by setting a
  3637. @code{LOG_INTO_DRAWER} property.
  3638. Since it is normally too much to record a note for every state, Org mode
  3639. expects configuration on a per-keyword basis for this. This is achieved by
  3640. adding special markers @samp{!} (for a timestamp) or @samp{@@} (for a note
  3641. with timestamp) in parentheses after each keyword. For example, with the
  3642. setting
  3643. @lisp
  3644. (setq org-todo-keywords
  3645. '((sequence "TODO(t)" "WAIT(w@@/!)" "|" "DONE(d!)" "CANCELED(c@@)")))
  3646. @end lisp
  3647. To record a timestamp without a note for TODO keywords configured with
  3648. @samp{@@}, just type @kbd{C-c C-c} to enter a blank note when prompted.
  3649. @noindent
  3650. @vindex org-log-done
  3651. you not only define global TODO keywords and fast access keys, but also
  3652. request that a time is recorded when the entry is set to
  3653. DONE@footnote{It is possible that Org mode will record two timestamps
  3654. when you are using both @code{org-log-done} and state change logging.
  3655. However, it will never prompt for two notes---if you have configured
  3656. both, the state change recording note will take precedence and cancel
  3657. the @samp{Closing Note}.}, and that a note is recorded when switching to
  3658. WAIT or CANCELED. The setting for WAIT is even more special: the
  3659. @samp{!} after the slash means that in addition to the note taken when
  3660. entering the state, a timestamp should be recorded when @i{leaving} the
  3661. WAIT state, if and only if the @i{target} state does not configure
  3662. logging for entering it. So it has no effect when switching from WAIT
  3663. to DONE, because DONE is configured to record a timestamp only. But
  3664. when switching from WAIT back to TODO, the @samp{/!} in the WAIT
  3665. setting now triggers a timestamp even though TODO has no logging
  3666. configured.
  3667. You can use the exact same syntax for setting logging preferences local
  3668. to a buffer:
  3669. @example
  3670. #+TODO: TODO(t) WAIT(w@@/!) | DONE(d!) CANCELED(c@@)
  3671. @end example
  3672. @cindex property, LOGGING
  3673. In order to define logging settings that are local to a subtree or a
  3674. single item, define a LOGGING property in this entry. Any non-empty
  3675. LOGGING property resets all logging settings to nil. You may then turn
  3676. on logging for this specific tree using STARTUP keywords like
  3677. @code{lognotedone} or @code{logrepeat}, as well as adding state specific
  3678. settings like @code{TODO(!)}. For example
  3679. @example

  3695. @cindex habits
  3696. Org has the ability to track the consistency of a special category of TODOs,
  3697. called ``habits''. A habit has the following properties:
  3698. @enumerate
  3699. @item
  3700. You have enabled the @code{habits} module by customizing the variable
  3701. @code{org-modules}.
  3702. @item
  3703. The habit is a TODO item, with a TODO keyword representing an open state.
  3704. @item
  3705. The property @code{STYLE} is set to the value @code{habit}.
  3706. @item
  3707. The TODO has a scheduled date, usually with a @code{.+} style repeat
  3708. interval. A @code{++} style may be appropriate for habits with time
  3709. constraints, e.g., must be done on weekends, or a @code{+} style for an
  3710. unusual habit that can have a backlog, e.g., weekly reports.
  3711. @item
  3712. The TODO may also have minimum and maximum ranges specified by using the
  3713. syntax @samp{.+2d/3d}, which says that you want to do the task at least every
  3714. three days, but at most every two days.
  3715. @item
  3716. You must also have state logging for the @code{DONE} state enabled
  3717. (@pxref{Tracking TODO state changes}), in order for historical data to be
  3718. represented in the consistency graph. If it is not enabled it is not an
  3719. error, but the consistency graphs will be largely meaningless.
  3720. @end enumerate
  3721. To give you an idea of what the above rules look like in action, here's an
  3722. actual habit with some history:
  3723. @example

  3739. :END:
  3740. @end example
  3741. What this habit says is: I want to shave at most every 2 days (given by the
  3742. @code{SCHEDULED} date and repeat interval) and at least every 4 days. If
  3743. today is the 15th, then the habit first appears in the agenda on Oct 17,
  3744. after the minimum of 2 days has elapsed, and will appear overdue on Oct 19,
  3745. after four days have elapsed.
  3746. What's really useful about habits is that they are displayed along with a
  3747. consistency graph, to show how consistent you've been at getting that task
  3748. done in the past. This graph shows every day that the task was done over the
  3749. past three weeks, with colors for each day. The colors used are:
  3750. @table @code
  3751. @item Blue
  3752. If the task wasn't to be done yet on that day.
  3753. @item Green
  3754. If the task could have been done on that day.
  3755. @item Yellow
  3756. If the task was going to be overdue the next day.
  3757. @item Red
  3758. If the task was overdue on that day.
  3759. @end table
  3760. In addition to coloring each day, the day is also marked with an asterisk if
  3761. the task was actually done that day, and an exclamation mark to show where
  3762. the current day falls in the graph.
  3763. There are several configuration variables that can be used to change the way
  3764. habits are displayed in the agenda.
  3765. @table @code
  3766. @item org-habit-graph-column
  3767. The buffer column at which the consistency graph should be drawn. This will
  3768. overwrite any text in that column, so it is a good idea to keep your habits'
  3769. titles brief and to the point.
  3770. @item org-habit-preceding-days
  3771. The amount of history, in days before today, to appear in consistency graphs.
  3772. @item org-habit-following-days
  3773. The number of days after today that will appear in consistency graphs.
  3774. @item org-habit-show-habits-only-for-today
  3775. If non-nil, only show habits in today's agenda view. This is set to true by
  3776. default.
  3777. @end table
  3778. Lastly, pressing @kbd{K} in the agenda buffer will cause habits to
  3779. temporarily be disabled and they won't appear at all. Press @kbd{K} again to
  3780. bring them back. They are also subject to tag filtering, if you have habits
  3781. which should only be done in certain contexts, for example.
  3782. @node Priorities, Breaking down tasks, Progress logging, TODO Items
  3783. @section Priorities
  3784. @cindex priorities
  3785. If you use Org mode extensively, you may end up with enough TODO items that
  3786. it starts to make sense to prioritize them. Prioritizing can be done by
  3787. placing a @emph{priority cookie} into the headline of a TODO item, like this
  3788. @example
  3789. *** TODO [#A] Write letter to Sam Fortune
  3790. @end example
  3791. @noindent
  3792. @vindex org-priority-faces
  3793. By default, Org mode supports three priorities: @samp{A}, @samp{B}, and
  3794. @samp{C}. @samp{A} is the highest priority. An entry without a cookie is
  3795. treated just like priority @samp{B}. Priorities make a difference only for
  3796. sorting in the agenda (@pxref{Weekly/daily agenda}); outside the agenda, they
  3797. have no inherent meaning to Org mode. The cookies can be highlighted with
  3798. special faces by customizing the variable @code{org-priority-faces}.
  3799. Priorities can be attached to any outline node; they do not need to be TODO
  3800. items.
  3801. @table @kbd
  3802. @item @kbd{C-c ,}
  3803. @kindex @kbd{C-c ,}
  3804. @findex org-priority
  3805. Set the priority of the current headline (@command{org-priority}). The
  3806. command prompts for a priority character @samp{A}, @samp{B} or @samp{C}.
  3807. When you press @key{SPC} instead, the priority cookie is removed from the
  3808. headline. The priorities can also be changed ``remotely'' from the timeline
  3809. and agenda buffer with the @kbd{,} command (@pxref{Agenda commands}).
  3810. @c
  3811. @orgcmdkkcc{S-@key{up},S-@key{down},org-priority-up,org-priority-down}

  3813. Increase/decrease priority of current headline@footnote{See also the option
  3814. @code{org-priority-start-cycle-with-default}.}. Note that these keys are
  3815. also used to modify timestamps (@pxref{Creating timestamps}). See also
  3816. @ref{Conflicts}, for a discussion of the interaction with
  3817. @code{shift-selection-mode}.
  3818. @end table
  3819. @vindex org-highest-priority
  3820. @vindex org-lowest-priority
  3821. @vindex org-default-priority
  3822. You can change the range of allowed priorities by setting the variables
  3823. @code{org-highest-priority}, @code{org-lowest-priority}, and
  3824. @code{org-default-priority}. For an individual buffer, you may set
  3825. these values (highest, lowest, default) like this (please make sure that
  3826. the highest priority is earlier in the alphabet than the lowest
  3827. priority):
  3828. @cindex #+PRIORITIES

  3830. #+PRIORITIES: A C B

  3834. @cindex tasks, breaking down
  3835. @cindex statistics, for TODO items
  3836. @vindex org-agenda-todo-list-sublevels
  3837. It is often advisable to break down large tasks into smaller, manageable
  3838. subtasks. You can do this by creating an outline tree below a TODO item,
  3839. with detailed subtasks on the tree@footnote{To keep subtasks out of the
  3840. global TODO list, see the @code{org-agenda-todo-list-sublevels}.}. To keep
  3841. the overview over the fraction of subtasks that are already completed, insert
  3842. either @samp{[/]} or @samp{[%]} anywhere in the headline. These cookies will
  3843. be updated each time the TODO status of a child changes, or when pressing
  3844. @kbd{C-c C-c} on the cookie. For example:
  3845. @example
  3846. * Organize Party [33%]
  3847. ** TODO Call people [1/2]
  3848. *** TODO Peter
  3849. *** DONE Sarah
  3850. ** TODO Buy food
  3851. ** DONE Talk to neighbor
  3852. @end example
  3853. @cindex property, COOKIE_DATA
  3854. If a heading has both checkboxes and TODO children below it, the meaning of
  3855. the statistics cookie become ambiguous. Set the property
  3856. @code{COOKIE_DATA} to either @samp{checkbox} or @samp{todo} to resolve
  3857. this issue.
  3858. @vindex org-hierarchical-todo-statistics
  3859. If you would like to have the statistics cookie count any TODO entries in the
  3860. subtree (not just direct children), configure the variable
  3861. @code{org-hierarchical-todo-statistics}. To do this for a single subtree,
  3862. include the word @samp{recursive} into the value of the @code{COOKIE_DATA}
  3863. property.
  3864. @example
  3865. * Parent capturing statistics [2/20]
  3866. :PROPERTIES:
  3867. :COOKIE_DATA: todo recursive
  3868. :END:
  3869. @end example
  3870. If you would like a TODO entry to automatically change to DONE
  3871. when all children are done, you can use the following setup:
  3872. @example
  3873. (defun org-summary-todo (n-done n-not-done)
  3874. "Switch entry to DONE when all subentries are done, to TODO otherwise."
  3875. (let (org-log-done org-log-states) ; turn off logging
  3876. (org-todo (if (= n-not-done 0) "DONE" "TODO"))))
  3877. (add-hook 'org-after-todo-statistics-hook 'org-summary-todo)
  3878. @end example
  3879. Another possibility is the use of checkboxes to identify (a hierarchy of) a
  3880. large number of subtasks (@pxref{Checkboxes}).
  3881. @node Checkboxes, , Breaking down tasks, TODO Items
  3882. @section Checkboxes
  3883. @cindex checkboxes
  3884. @vindex org-list-automatic-rules
  3885. Every item in a plain list@footnote{With the exception of description
  3886. lists. But you can allow it by modifying @code{org-list-automatic-rules}
  3887. accordingly.} (@pxref{Plain lists}) can be made into a checkbox by starting
  3888. it with the string @samp{[ ]}. This feature is similar to TODO items
  3889. (@pxref{TODO Items}), but is more lightweight. Checkboxes are not included
  3890. into the global TODO list, so they are often great to split a task into a
  3891. number of simple steps. Or you can use them in a shopping list. To toggle a
  3892. checkbox, use @kbd{C-c C-c}, or use the mouse (thanks to Piotr Zielinski's
  3893. @file{org-mouse.el}).
  3894. Here is an example of a checkbox list.
  3895. @example
  3896. * TODO Organize party [2/4]
  3897. - [-] call people [1/3]
  3898. - [ ] Peter
  3899. - [X] Sarah
  3900. - [ ] Sam
  3901. - [X] order food
  3902. - [ ] think about what music to play
  3903. - [X] talk to the neighbors
  3904. @end example
  3905. Checkboxes work hierarchically, so if a checkbox item has children that
  3906. are checkboxes, toggling one of the children checkboxes will make the
  3907. parent checkbox reflect if none, some, or all of the children are
  3908. checked.
  3909. @cindex statistics, for checkboxes
  3910. @cindex checkbox statistics
  3911. @cindex property, COOKIE_DATA
  3912. @vindex org-hierarchical-checkbox-statistics
  3913. The @samp{[2/4]} and @samp{[1/3]} in the first and second line are cookies
  3914. indicating how many checkboxes present in this entry have been checked off,
  3915. and the total number of checkboxes present. This can give you an idea on how
  3916. many checkboxes remain, even without opening a folded entry. The cookies can
  3917. be placed into a headline or into (the first line of) a plain list item.
  3918. Each cookie covers checkboxes of direct children structurally below the
  3919. headline/item on which the cookie appears@footnote{Set the variable
  3920. @code{org-hierarchical-checkbox-statistics} if you want such cookies to
  3921. count all checkboxes below the cookie, not just those belonging to direct
  3922. children.}. You have to insert the cookie yourself by typing either
  3923. @samp{[/]} or @samp{[%]}. With @samp{[/]} you get an @samp{n out of m}
  3924. result, as in the examples above. With @samp{[%]} you get information about
  3925. the percentage of checkboxes checked (in the above example, this would be
  3926. @samp{[50%]} and @samp{[33%]}, respectively). In a headline, a cookie can
  3927. count either checkboxes below the heading or TODO states of children, and it
  3928. will display whatever was changed last. Set the property @code{COOKIE_DATA}
  3929. to either @samp{checkbox} or @samp{todo} to resolve this issue.
  3930. @cindex blocking, of checkboxes
  3931. @cindex checkbox blocking
  3932. @cindex property, ORDERED
  3933. If the current outline node has an @code{ORDERED} property, checkboxes must
  3934. be checked off in sequence, and an error will be thrown if you try to check
  3935. off a box while there are unchecked boxes above it.
  3936. @noindent The following commands work with checkboxes:
  3937. @table @kbd
  3938. @orgcmd{C-c C-c,org-toggle-checkbox}
  3939. Toggle checkbox status or (with prefix arg) checkbox presence at point.
  3940. With a single prefix argument, add an empty checkbox or remove the current
  3941. one@footnote{`C-u C-c C-c' on the @emph{first} item of a list with no checkbox
  3942. will add checkboxes to the rest of the list.}. With a double prefix argument, set it to @samp{[-]}, which is
  3943. considered to be an intermediate state.
  3944. @orgcmd{C-c C-x C-b,org-toggle-checkbox}
  3945. Toggle checkbox status or (with prefix arg) checkbox presence at point. With
  3946. double prefix argument, set it to @samp{[-]}, which is considered to be an
  3947. intermediate state.
  3948. @itemize @minus
  3949. @item
  3950. If there is an active region, toggle the first checkbox in the region
  3951. and set all remaining boxes to the same status as the first. With a prefix
  3952. arg, add or remove the checkbox for all items in the region.
  3953. @item
  3954. If the cursor is in a headline, toggle checkboxes in the region between
  3955. this headline and the next (so @emph{not} the entire subtree).
  3956. @item
  3957. If there is no active region, just toggle the checkbox at point.
  3958. @end itemize
  3959. @orgcmd{M-S-@key{RET},org-insert-todo-heading}
  3960. Insert a new item with a checkbox. This works only if the cursor is already
  3961. in a plain list item (@pxref{Plain lists}).
  3962. @orgcmd{C-c C-x o,org-toggle-ordered-property}
  3963. @vindex org-track-ordered-property-with-tag
  3964. @cindex property, ORDERED
  3965. Toggle the @code{ORDERED} property of the entry, to toggle if checkboxes must
  3966. be checked off in sequence. A property is used for this behavior because
  3967. this should be local to the current entry, not inherited like a tag.
  3968. However, if you would like to @i{track} the value of this property with a tag
  3969. for better visibility, customize the variable
  3970. @code{org-track-ordered-property-with-tag}.
  3971. @orgcmd{C-c #,org-update-statistics-cookies}
  3972. Update the statistics cookie in the current outline entry. When called with
  3973. a @kbd{C-u} prefix, update the entire file. Checkbox statistic cookies are
  3974. updated automatically if you toggle checkboxes with @kbd{C-c C-c} and make
  3975. new ones with @kbd{M-S-@key{RET}}. TODO statistics cookies update when
  3976. changing TODO states. If you delete boxes/entries or add/change them by
  3977. hand, use this command to get things back into sync.

  3991. @samp{@@}. Tags must be preceded and followed by a single colon, e.g.,
  3992. @samp{:work:}. Several tags can be specified, as in @samp{:work:urgent:}.
  3993. Tags will by default be in bold face with the same color as the headline.
  3994. You may specify special faces for specific tags using the variable
  3995. @code{org-tag-faces}, in much the same way as you can for TODO keywords
  3996. (@pxref{Faces for TODO keywords}).

  4017. @samp{:notes:}, and @samp{:action:} even though the final heading is not
  4018. explicitly marked with those tags. You can also set tags that all entries in
  4019. a file should inherit just as if these tags were defined in a hypothetical
  4020. level zero that surrounds the entire file. Use a line like this@footnote{As
  4021. with all these in-buffer settings, pressing @kbd{C-c C-c} activates any
  4022. changes in the line.}:
  4023. @cindex #+FILETAGS

  4033. @vindex org-tags-match-list-sublevels
  4034. When a headline matches during a tags search while tag inheritance is turned

  4036. as well@footnote{This is only true if the search does not involve more
  4037. complex tests including properties (@pxref{Property searches}).}. The list
  4038. of matches may then become very long. If you only want to see the first tags

  4051. @cindex completion, of tags
  4052. @vindex org-tags-column
  4053. Enter new tags for the current headline. Org mode will either offer
  4054. completion or a special single-key interface for setting tags, see
  4055. below. After pressing @key{RET}, the tags will be inserted and aligned
  4056. to @code{org-tags-column}. When called with a @kbd{C-u} prefix, all
  4057. tags in the current buffer will be aligned to that column, just to make
  4058. things look nice. TAGS are automatically realigned after promotion,
  4059. demotion, and TODO state changes (@pxref{TODO basics}).
  4060. @orgcmd{C-c C-c,org-set-tags-command}
  4061. When the cursor is in a headline, this does the same as @kbd{C-c C-q}.
  4062. @end table
  4063. @vindex org-tag-alist
  4064. Org supports tag insertion based on a @emph{list of tags}. By
  4065. default this list is constructed dynamically, containing all tags
  4066. currently used in the buffer. You may also globally specify a hard list
  4067. of tags with the variable @code{org-tag-alist}. Finally you can set
  4068. the default tags for a given file with lines like
  4069. @cindex #+TAGS
  4070. @example
  4071. #+TAGS: @@work @@home @@tennisclub
  4072. #+TAGS: laptop car pc sailboat
  4073. @end example
  4074. If you have globally defined your preferred set of tags using the
  4075. variable @code{org-tag-alist}, but would like to use a dynamic tag list
  4076. in a specific file, add an empty TAGS option line to that file:
  4077. @example
  4078. #+TAGS:
  4079. @end example
  4080. @vindex org-tag-persistent-alist
  4081. If you have a preferred set of tags that you would like to use in every file,
  4082. in addition to those defined on a per-file basis by TAGS option lines, then
  4083. you may specify a list of tags with the variable
  4084. @code{org-tag-persistent-alist}. You may turn this off on a per-file basis
  4085. by adding a STARTUP option line to that file:
  4086. @example
  4087. #+STARTUP: noptag
  4088. @end example
  4089. By default Org mode uses the standard minibuffer completion facilities for
  4090. entering tags. However, it also implements another, quicker, tag selection
  4091. method called @emph{fast tag selection}. This allows you to select and
  4092. deselect tags with just a single key press. For this to work well you should
  4093. assign unique letters to most of your commonly used tags. You can do this
  4094. globally by configuring the variable @code{org-tag-alist} in your
  4095. @file{.emacs} file. For example, you may find the need to tag many items in
  4096. different files with @samp{:@@home:}. In this case you can set something
  4097. like:
  4098. @lisp
  4099. (setq org-tag-alist '(("@@work" . ?w) ("@@home" . ?h) ("laptop" . ?l)))
  4100. @end lisp
  4101. @noindent If the tag is only relevant to the file you are working on, then you
  4102. can instead set the TAGS option line as:
  4103. @example
  4104. #+TAGS: @@work(w) @@home(h) @@tennisclub(t) laptop(l) pc(p)
  4105. @end example
  4106. @noindent The tags interface will show the available tags in a splash
  4107. window. If you want to start a new line after a specific tag, insert
  4108. @samp{\n} into the tag list
  4109. @example
  4110. #+TAGS: @@work(w) @@home(h) @@tennisclub(t) \n laptop(l) pc(p)
  4111. @end example
  4112. @noindent or write them in two lines:
  4113. @example
  4114. #+TAGS: @@work(w) @@home(h) @@tennisclub(t)
  4115. #+TAGS: laptop(l) pc(p)
  4116. @end example
  4117. @noindent
  4118. You can also group together tags that are mutually exclusive by using
  4119. braces, as in:
  4120. @example
  4121. #+TAGS: @{ @@work(w) @@home(h) @@tennisclub(t) @} laptop(l) pc(p)
  4122. @end example
  4123. @noindent you indicate that at most one of @samp{@@work}, @samp{@@home},
  4124. and @samp{@@tennisclub} should be selected. Multiple such groups are allowed.
  4125. @noindent Don't forget to press @kbd{C-c C-c} with the cursor in one of
  4126. these lines to activate any changes.
  4127. @noindent
  4128. To set these mutually exclusive groups in the variable @code{org-tags-alist},
  4129. you must use the dummy tags @code{:startgroup} and @code{:endgroup} instead
  4130. of the braces. Similarly, you can use @code{:newline} to indicate a line
  4131. break. The previous example would be set globally by the following
  4132. configuration:
  4133. @lisp
  4134. (setq org-tag-alist '((:startgroup . nil)
  4135. ("@@work" . ?w) ("@@home" . ?h)
  4136. ("@@tennisclub" . ?t)
  4137. (:endgroup . nil)
  4138. ("laptop" . ?l) ("pc" . ?p)))
  4139. @end lisp
  4140. If at least one tag has a selection key then pressing @kbd{C-c C-c} will
  4141. automatically present you with a special interface, listing inherited tags,
  4142. the tags of the current headline, and a list of all valid tags with
  4143. corresponding keys@footnote{Keys will automatically be assigned to tags which
  4144. have no configured keys.}. In this interface, you can use the following
  4145. keys:
  4146. @table @kbd
  4147. @item a-z...
  4148. Pressing keys assigned to tags will add or remove them from the list of
  4149. tags in the current line. Selecting a tag in a group of mutually
  4150. exclusive tags will turn off any other tags from that group.
  4151. @kindex @key{TAB}
  4152. @item @key{TAB}
  4153. Enter a tag in the minibuffer, even if the tag is not in the predefined
  4154. list. You will be able to complete on all tags present in the buffer.
  4155. You can also add several tags: just separate them with a comma.
  4156. @kindex @key{SPC}
  4157. @item @key{SPC}
  4158. Clear all tags for this line.
  4159. @kindex @key{RET}
  4160. @item @key{RET}
  4161. Accept the modified set.
  4162. @item C-g
  4163. Abort without installing changes.
  4164. @item q

  4175. This method lets you assign tags to a headline with very few keys. With
  4176. the above setup, you could clear the current tags and set @samp{@@home},
  4177. @samp{laptop} and @samp{pc} tags with just the following keys: @kbd{C-c
  4178. C-c @key{SPC} h l p @key{RET}}. Switching from @samp{@@home} to
  4179. @samp{@@work} would be done with @kbd{C-c C-c w @key{RET}} or
  4180. alternatively with @kbd{C-c C-c C-c w}. Adding the non-predefined tag
  4181. @samp{Sarah} could be done with @kbd{C-c C-c @key{TAB} S a r a h
  4182. @key{RET} @key{RET}}.

  4185. modify your list of tags, set the variable
  4186. @code{org-fast-tag-selection-single-key}. Then you no longer have to
  4187. press @key{RET} to exit fast tag selection---it will immediately exit
  4188. after the first change. If you then occasionally need more keys, press
  4189. @kbd{C-c} to turn off auto-exit for the current tag selection process
  4190. (in effect: start selection with @kbd{C-c C-c C-c} instead of @kbd{C-c
  4191. C-c}). If you set the variable to the value @code{expert}, the special

  4220. @node Properties and Columns, Dates and Times, Tags, Top
  4221. @chapter Properties and columns
  4222. @cindex properties
  4223. A property is a key-value pair associated with an entry. Properties can be
  4224. set so they are associated with a single entry, with every entry in a tree,
  4225. or with every entry in an Org mode file.
  4226. There are two main applications for properties in Org mode. First,
  4227. properties are like tags, but with a value. Imagine maintaining a file where
  4228. you document bugs and plan releases for a piece of software. Instead of
  4229. using tags like @code{:release_1:}, @code{:release_2:}, you can use a
  4230. property, say @code{:Release:}, that in different subtrees has different
  4231. values, such as @code{1.0} or @code{2.0}. Second, you can use properties to
  4232. implement (very basic) database capabilities in an Org buffer. Imagine
  4233. keeping track of your music CDs, where properties could be things such as the
  4234. album, artist, date of release, number of tracks, and so on.
  4235. Properties can be conveniently edited and viewed in column view
  4236. (@pxref{Column view}).

  4248. @cindex drawer, for properties
  4249. Properties are key-value pairs. When they are associated with a single entry
  4250. or with a tree they need to be inserted into a special
  4251. drawer (@pxref{Drawers}) with the name @code{PROPERTIES}. Each property
  4252. is specified on a single line, with the key (surrounded by colons)
  4253. first, and the value after it. Here is an example:
  4254. @example
  4255. * CD collection
  4256. ** Classic
  4257. *** Goldberg Variations
  4258. :PROPERTIES:
  4259. :Title: Goldberg Variations

  4263. :NDisks: 1
  4264. :END:
  4265. @end example
  4266. Depending on the value of @code{org-use-property-inheritance}, a property set
  4267. this way will either be associated with a single entry, or the sub-tree
  4268. defined by the entry, see @ref{Property inheritance}.
  4269. You may define the allowed values for a particular property @samp{:Xyz:}
  4270. by setting a property @samp{:Xyz_ALL:}. This special property is
  4271. @emph{inherited}, so if you set it in a level 1 entry, it will apply to
  4272. the entire tree. When allowed values are defined, setting the
  4273. corresponding property becomes easier and is less prone to typing
  4274. errors. For the example with the CD collection, we can predefine
  4275. publishers and the number of disks in a box like this:
  4276. @example
  4277. * CD collection
  4278. :PROPERTIES:
  4279. :NDisks_ALL: 1 2 3 4
  4280. :Publisher_ALL: "Deutsche Grammophon" Philips EMI
  4281. :END:
  4282. @end example
  4283. If you want to set properties that can be inherited by any entry in a
  4284. file, use a line like
  4285. @cindex property, _ALL
  4286. @cindex #+PROPERTY
  4287. @example
  4288. #+PROPERTY: NDisks_ALL 1 2 3 4
  4289. @end example
  4290. If you want to add to the value of an existing property, append a @code{+} to
  4291. the property name. The following results in the property @code{var} having
  4292. the value ``foo=1 bar=2''.
  4293. @cindex property, +
  4294. @example
  4295. #+PROPERTY: var foo=1
  4296. #+PROPERTY: var+ bar=2
  4297. @end example
  4298. It is also possible to add to the values of inherited properties. The
  4299. following results in the @code{genres} property having the value ``Classic
  4300. Baroque'' under the @code{Goldberg Variations} subtree.
  4301. @cindex property, +

  4423. @table @kbd
  4424. @orgkey{C-c / p}
  4425. Create a sparse tree based on the value of a property. This first
  4426. prompts for the name of a property, and then for a value. A sparse tree
  4427. is created with all entries that define this property with the given
  4428. value. If you enclose the value in curly braces, it is interpreted as
  4429. a regular expression and matched against the property values.

  4436. The outline structure of Org mode documents lends itself to an
  4437. inheritance model of properties: if the parent in a tree has a certain
  4438. property, the children can inherit this property. Org mode does not
  4439. turn this on by default, because it can slow down property searches
  4440. significantly and is often not needed. However, if you find inheritance
  4441. useful, you can turn it on by setting the variable
  4442. @code{org-use-property-inheritance}. It may be set to @code{t} to make
  4443. all properties inherited from the parent, to a list of properties
  4444. that should be inherited, or to a regular expression that matches
  4445. inherited properties. If a property has the value @samp{nil}, this is
  4446. interpreted as an explicit undefine of the property, so that inheritance
  4447. search will stop at this value and return @code{nil}.
  4448. Org mode has a few properties for which inheritance is hard-coded, at
  4449. least for the special applications for which they are used:
  4450. @cindex property, COLUMNS
  4451. @table @code
  4452. @item COLUMNS
  4453. The @code{:COLUMNS:} property defines the format of column view
  4454. (@pxref{Column view}). It is inherited in the sense that the level
  4455. where a @code{:COLUMNS:} property is defined is used as the starting
  4456. point for a column view table, independently of the location in the
  4457. subtree from where columns view is turned on.
  4458. @item CATEGORY
  4459. @cindex property, CATEGORY
  4460. For agenda view, a category set through a @code{:CATEGORY:} property
  4461. applies to the entire subtree.
  4462. @item ARCHIVE
  4463. @cindex property, ARCHIVE
  4464. For archiving, the @code{:ARCHIVE:} property may define the archive
  4465. location for the entire subtree (@pxref{Moving subtrees}).
  4466. @item LOGGING
  4467. @cindex property, LOGGING
  4468. The LOGGING property may define logging settings for an entry or a
  4469. subtree (@pxref{Tracking TODO state changes}).
  4470. @end table
  4471. @node Column view, Property API, Property inheritance, Properties and Columns
  4472. @section Column view
  4473. A great way to view and edit properties in an outline tree is
  4474. @emph{column view}. In column view, each outline node is turned into a
  4475. table row. Columns in this table provide access to properties of the
  4476. entries. Org mode implements columns by overlaying a tabular structure
  4477. over the headline of each item. While the headlines have been turned
  4478. into a table row, you can still change the visibility of the outline
  4479. tree. For example, you get a compact table by switching to CONTENTS
  4480. view (@kbd{S-@key{TAB} S-@key{TAB}}, or simply @kbd{c} while column view
  4481. is active), but you can still open, read, and edit the entry below each
  4482. headline. Or, you can switch to column view after executing a sparse
  4483. tree command and in this way get a table only for the selected items.
  4484. Column view also works in agenda buffers (@pxref{Agenda Views}) where
  4485. queries have collected selected items, possibly from a number of files.

  4506. #+COLUMNS: %25ITEM %TAGS %PRIORITY %TODO
  4507. @end example
  4508. To specify a format that only applies to a specific tree, add a
  4509. @code{:COLUMNS:} property to the top node of that tree, for example:

  4516. If a @code{:COLUMNS:} property is present in an entry, it defines columns
  4517. for the entry itself, and for the entire subtree below it. Since the
  4518. column definition is part of the hierarchical structure of the document,
  4519. you can define columns on level 1 that are general enough for all
  4520. sublevels, and more specific columns further down, when you edit a
  4521. deeper part of the tree.
  4522. @node Column attributes, , Scope of column definitions, Defining columns

  4561. @noindent
  4562. Be aware that you can only have one summary type for any property you
  4563. include. Subsequent columns referencing the same property will all display the
  4564. same summary information.
  4565. The @code{est+} summary type requires further explanation. It is used for
  4566. combining estimates, expressed as low-high ranges. For example, instead
  4567. of estimating a particular task will take 5 days, you might estimate it as
  4568. 5-6 days if you're fairly confident you know how much work is required, or
  4569. 1-10 days if you don't really know what needs to be done. Both ranges
  4570. average at 5.5 days, but the first represents a more predictable delivery.
  4571. When combining a set of such estimates, simply adding the lows and highs
  4572. produces an unrealistically wide result. Instead, @code{est+} adds the
  4573. statistical mean and variance of the sub-tasks, generating a final estimate
  4574. from the sum. For example, suppose you had ten tasks, each of which was
  4575. estimated at 0.5 to 2 days of work. Straight addition produces an estimate
  4576. of 5 to 20 days, representing what to expect if everything goes either
  4577. extremely well or extremely poorly. In contrast, @code{est+} estimates the
  4578. full job more realistically, at 10-15 days.
  4579. Here is an example for a complete columns definition, along with allowed
  4580. values.
  4581. @example
  4582. :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.}
  4583. %10Time_Estimate@{:@} %CLOCKSUM %CLOCKSUM_T
  4584. :Owner_ALL: Tammy Mark Karl Lisa Don
  4585. :Status_ALL: "In progress" "Not started yet" "Finished" ""
  4586. :Approved_ALL: "[ ]" "[X]"
  4587. @end example
  4588. @noindent
  4589. The first column, @samp{%25ITEM}, means the first 25 characters of the
  4590. item itself, i.e.@: of the headline. You probably always should start the
  4591. column definition with the @samp{ITEM} specifier. The other specifiers
  4592. create columns @samp{Owner} with a list of names as allowed values, for
  4593. @samp{Status} with four different possible values, and for a checkbox
  4594. field @samp{Approved}. When no width is given after the @samp{%}
  4595. character, the column will be exactly as wide as it needs to be in order
  4596. to fully display all values. The @samp{Approved} column does have a
  4597. modified title (@samp{Approved?}, with a question mark). Summaries will
  4598. be created for the @samp{Time_Estimate} column by adding time duration
  4599. expressions like HH:MM, and for the @samp{Approved} column, by providing
  4600. an @samp{[X]} status if all children have been checked. The
  4601. @samp{CLOCKSUM} and @samp{CLOCKSUM_T} columns are special, they lists the
  4602. sums of CLOCK intervals in the subtree, either for all clocks or just for
  4603. today.

  4661. @subsection Capturing column view
  4662. Since column view is just an overlay over a buffer, it cannot be
  4663. exported or printed directly. If you want to capture a column view, use
  4664. a @code{columnview} dynamic block (@pxref{Dynamic blocks}). The frame
  4665. of this block looks like this:
  4666. @cindex #+BEGIN, columnview
  4667. @example
  4668. * The column view
  4669. #+BEGIN: columnview :hlines 1 :id "label"
  4670. #+END:
  4671. @end example
  4672. @noindent This dynamic block has the following parameters:
  4673. @table @code
  4674. @item :id
  4675. This is the most important parameter. Column view is a feature that is
  4676. often localized to a certain (sub)tree, and the capture block might be
  4677. at a different location in the file. To identify the tree whose view to
  4678. capture, you can use 4 values:
  4679. @cindex property, ID
  4680. @example
  4681. local @r{use the tree in which the capture block is located}
  4682. global @r{make a global view, including all headings in the file}
  4683. "file:@var{path-to-file}"
  4684. @r{run column view at the top of this file}
  4685. "@var{ID}" @r{call column view in the tree that has an @code{:ID:}}
  4686. @r{property with the value @i{label}. You can use}
  4687. @r{@kbd{M-x org-id-copy} to create a globally unique ID for}
  4688. @r{the current entry and copy it to the kill-ring.}
  4689. @end example
  4690. @item :hlines
  4691. When @code{t}, insert an hline after every line. When a number @var{N}, insert
  4692. an hline before each headline with level @code{<= @var{N}}.
  4693. @item :vlines
  4694. When set to @code{t}, force column groups to get vertical lines.
  4695. @item :maxlevel
  4696. When set to a number, don't capture entries below this level.
  4697. @item :skip-empty-rows
  4698. When set to @code{t}, skip rows where the only non-empty specifier of the
  4699. column view is @code{ITEM}.

  4702. The following commands insert or update the dynamic block:
  4703. @table @kbd
  4704. @orgcmd{C-c C-x i,org-insert-columns-dblock}
  4705. Insert a dynamic block capturing a column view. You will be prompted
  4706. for the scope or ID of the view.
  4707. @orgcmdkkc{C-c C-c,C-c C-x C-u,org-dblock-update}
  4708. Update dynamic block at point. The cursor needs to be in the
  4709. @code{#+BEGIN} line of the dynamic block.
  4710. @orgcmd{C-u C-c C-x C-u,org-update-all-dblocks}
  4711. Update all dynamic blocks (@pxref{Dynamic blocks}). This is useful if
  4712. you have several clock table blocks, column-capturing blocks or other dynamic
  4713. blocks in a buffer.
  4714. @end table
  4715. You can add formulas to the column view table and you may add plotting
  4716. instructions in front of the table---these will survive an update of the
  4717. block. If there is a @code{#+TBLFM:} after the table, the table will
  4718. actually be recalculated automatically after an update.
  4719. An alternative way to capture and process property values into a table is
  4720. provided by Eric Schulte's @file{org-collector.el} which is a contributed
  4721. package@footnote{Contributed packages are not part of Emacs, but are
  4722. distributed with the main distribution of Org (visit
  4723. @uref{http://orgmode.org}).}. It provides a general API to collect

  4743. little confusing because timestamp is often used as indicating when

  4762. A timestamp is a specification of a date (possibly with a time or a range of
  4763. times) in a special format, either @samp{<2003-09-16 Tue>}@footnote{In this
  4764. simplest form, the day name is optional when you type the date yourself.
  4765. However, any dates inserted or modified by Org will add that day name, for
  4766. reading convenience.} or @samp{<2003-09-16 Tue 09:39>} or @samp{<2003-09-16
  4767. Tue 12:00-12:30>}@footnote{This is inspired by the standard ISO 8601
  4768. date/time format. To use an alternative format, see @ref{Custom time
  4769. format}.}. A timestamp can appear anywhere in the headline or body of an Org
  4770. tree entry. Its presence causes entries to be shown on specific dates in the
  4771. agenda (@pxref{Weekly/daily agenda}). We distinguish:
  4772. @table @var
  4773. @item Plain timestamp; Event; Appointment
  4774. @cindex timestamp
  4775. @cindex appointment
  4776. A simple timestamp just assigns a date/time to an item. This is just
  4777. like writing down an appointment or event in a paper agenda. In the
  4778. timeline and agenda displays, the headline of an entry associated with a
  4779. plain timestamp will be shown exactly on that date.
  4780. @example
  4781. * Meet Peter at the movies
  4782. <2006-11-01 Wed 19:15>
  4783. * Discussion on climate change

  4785. @end example
  4786. @item Timestamp with repeater interval
  4787. @cindex timestamp, with repeater interval
  4788. A timestamp may contain a @emph{repeater interval}, indicating that it
  4789. applies not only on the given date, but again and again after a certain
  4790. interval of N days (d), weeks (w), months (m), or years (y). The
  4791. following will show up in the agenda every Wednesday:
  4792. @example
  4793. * Pick up Sam at school
  4794. <2007-05-16 Wed 12:30 +1w>
  4795. @end example
  4796. @item Diary-style sexp entries
  4797. For more complex date specifications, Org mode supports using the special
  4798. sexp diary entries implemented in the Emacs calendar/diary
  4799. package@footnote{When working with the standard diary sexp functions, you
  4800. need to be very careful with the order of the arguments. That order depend
  4801. evilly on the variable @code{calendar-date-style} (or, for older Emacs
  4802. versions, @code{european-calendar-style}). For example, to specify a date
  4803. December 12, 2005, the call might look like @code{(diary-date 12 1 2005)} or
  4804. @code{(diary-date 1 12 2005)} or @code{(diary-date 2005 12 1)}, depending on
  4805. the settings. This has been the source of much confusion. Org mode users
  4806. can resort to special versions of these functions like @code{org-date} or
  4807. @code{org-anniversary}. These work just like the corresponding @code{diary-}
  4808. functions, but with stable ISO order of arguments (year, month, day) wherever
  4809. applicable, independent of the value of @code{calendar-date-style}.}. For
  4810. example with optional time
  4811. @example
  4812. * 22:00-23:00 The nerd meeting on every 2nd Thursday of the month
  4813. <%%(org-float t 4 2)>

  4815. @item Time/Date range
  4816. @cindex timerange
  4817. @cindex date range
  4818. Two timestamps connected by @samp{--} denote a range. The headline
  4819. will be shown on the first and last day of the range, and on any dates
  4820. that are displayed and fall in the range. Here is an example:
  4821. @example
  4822. ** Meeting in Amsterdam
  4823. <2004-08-23 Mon>--<2004-08-26 Thu>
  4824. @end example
  4825. @item Inactive timestamp
  4826. @cindex timestamp, inactive
  4827. @cindex inactive timestamp
  4828. Just like a plain timestamp, but with square brackets instead of
  4829. angular ones. These timestamps are inactive in the sense that they do
  4830. @emph{not} trigger an entry to show up in the agenda.

  4907. When Org mode prompts for a date/time, the default is shown in default
  4908. date/time format, and the prompt therefore seems to ask for a specific
  4909. format. But it will in fact accept any string containing some date and/or
  4910. time information, and it is really smart about interpreting your input. You
  4911. can, for example, use @kbd{C-y} to paste a (possibly multi-line) string
  4912. copied from an email message. Org mode will find whatever information is in
  4913. there and derive anything you have not specified from the @emph{default date
  4914. and time}. The default is usually the current date and time, but when
  4915. modifying an existing timestamp, or when entering the second stamp of a
  4916. range, it is taken from the stamp in the buffer. When filling in
  4917. information, Org mode assumes that most of the time you will want to enter a
  4918. date in the future: if you omit the month/year and the given day/month is
  4919. @i{before} today, it will assume that you mean a future date@footnote{See the
  4920. variable @code{org-read-date-prefer-future}. You may set that variable to
  4921. the symbol @code{time} to even make a time before now shift the date to
  4922. tomorrow.}. If the date has been automatically shifted into the future, the
  4923. time prompt will show this with @samp{(=>F).}
  4924. For example, let's assume that today is @b{June 13, 2006}. Here is how
  4925. various inputs will be interpreted, the items filled in by Org mode are

  5177. Some tasks need to be repeated again and again. Org mode helps to
  5178. organize such tasks using a so-called repeater in a DEADLINE, SCHEDULED,
  5179. or plain timestamp. In the following example
  5180. @example
  5181. ** TODO Pay the rent
  5182. DEADLINE: <2005-10-01 Sat +1m>
  5183. @end example
  5184. @noindent
  5185. the @code{+1m} is a repeater; the intended interpretation is that the task
  5186. has a deadline on <2005-10-01> and repeats itself every (one) month starting
  5187. from that time. You can use yearly, monthly, weekly, daily and hourly repeat
  5188. cookies by using the @code{y/w/m/d/h} letters. If you need both a repeater
  5189. and a special warning period in a deadline entry, the repeater should come
  5190. first and the warning period last: @code{DEADLINE: <2005-10-01 Sat +1m -3d>}.
  5191. @vindex org-todo-repeat-to-state
  5192. Deadlines and scheduled items produce entries in the agenda when they are
  5193. over-due, so it is important to be able to mark such an entry as completed
  5194. once you have done so. When you mark a DEADLINE or a SCHEDULE with the TODO
  5195. keyword DONE, it will no longer produce entries in the agenda. The problem
  5196. with this is, however, that then also the @emph{next} instance of the
  5197. repeated entry will not be active. Org mode deals with this in the following
  5198. way: When you try to mark such an entry DONE (using @kbd{C-c C-t}), it will
  5199. shift the base date of the repeating timestamp by the repeater interval, and
  5200. immediately set the entry state back to TODO@footnote{In fact, the target
  5201. state is taken from, in this sequence, the @code{REPEAT_TO_STATE} property or
  5202. the variable @code{org-todo-repeat-to-state}. If neither of these is
  5203. specified, the target state defaults to the first state of the TODO state
  5204. sequence.}. In the example above, setting the state to DONE would actually
  5205. switch the date like this:
  5206. @example
  5207. ** TODO Pay the rent
  5208. DEADLINE: <2005-11-01 Tue +1m>
  5209. @end example
  5210. @vindex org-log-repeat
  5211. A timestamp@footnote{You can change this using the option
  5212. @code{org-log-repeat}, or the @code{#+STARTUP} options @code{logrepeat},
  5213. @code{lognoterepeat}, and @code{nologrepeat}. With @code{lognoterepeat}, you
  5214. will also be prompted for a note.} will be added under the deadline, to keep
  5215. a record that you actually acted on the previous instance of this deadline.
  5216. As a consequence of shifting the base date, this entry will no longer be
  5217. visible in the agenda when checking past dates, but all future instances
  5218. will be visible.
  5219. With the @samp{+1m} cookie, the date shift will always be exactly one
  5220. month. So if you have not paid the rent for three months, marking this
  5221. entry DONE will still keep it as an overdue deadline. Depending on the
  5222. task, this may not be the best way to handle it. For example, if you
  5223. forgot to call your father for 3 weeks, it does not make sense to call
  5224. him 3 times in a single day to make up for it. Finally, there are tasks
  5225. like changing batteries which should always repeat a certain time
  5226. @i{after} the last time you did it. For these tasks, Org mode has
  5227. special repeaters @samp{++} and @samp{.+}. For example:
  5228. @example
  5229. ** TODO Call Father
  5230. DEADLINE: <2008-02-10 Sun ++1w>
  5231. Marking this DONE will shift the date by at least one week,
  5232. but also by as many weeks as it takes to get this date into
  5233. the future. However, it stays on a Sunday, even if you called
  5234. and marked it done on Saturday.
  5235. ** TODO Check the batteries in the smoke detectors
  5236. DEADLINE: <2005-11-01 Tue .+1m>
  5237. Marking this DONE will shift the date to one month after
  5238. today.
  5239. @end example
  5240. You may have both scheduling and deadline information for a specific
  5241. task---just make sure that the repeater intervals on both are the same.
  5242. An alternative to using a repeater is to create a number of copies of a task
  5243. subtree, with dates shifted in each copy. The command @kbd{C-c C-x c} was
  5244. created for this purpose, it is described in @ref{Structure editing}.

  5339. @orgcmd{S-M-@key{up/down},org-timestamp-up/down}
  5340. On @code{CLOCK} log lines, increase/decrease the timestamp at point and
  5341. the one of the previous (or the next clock) timestamp by the same duration.
  5342. For example, if you hit @kbd{S-M-@key{up}} to increase a clocked-out timestamp
  5343. by five minutes, then the clocked-in timestamp of the next clock will be
  5344. increased by five minutes.

  5501. @cindex idle, resolve, dangling
  5502. If you clock in on a work item, and then walk away from your
  5503. computer---perhaps to take a phone call---you often need to ``resolve'' the
  5504. time you were away by either subtracting it from the current clock, or
  5505. applying it to another one.
  5506. @vindex org-clock-idle-time
  5507. By customizing the variable @code{org-clock-idle-time} to some integer, such
  5508. as 10 or 15, Emacs can alert you when you get back to your computer after
  5509. being idle for that many minutes@footnote{On computers using Mac OS X,
  5510. idleness is based on actual user idleness, not just Emacs' idle time. For
  5511. X11, you can install a utility program @file{x11idle.c}, available in the
  5512. @code{contrib/scripts} directory of the Org git distribution, to get the same
  5513. general treatment of idleness. On other systems, idle time refers to Emacs
  5514. idle time only.}, and ask what you want to do with the idle time. There will
  5515. be a question waiting for you when you get back, indicating how much idle
  5516. time has passed (constantly updated with the current amount), as well as a
  5517. set of choices to correct the discrepancy:
  5518. @table @kbd
  5519. @item k
  5520. To keep some or all of the minutes and stay clocked in, press @kbd{k}. Org
  5521. will ask how many of the minutes to keep. Press @key{RET} to keep them all,
  5522. effectively changing nothing, or enter a number to keep that many minutes.
  5523. @item K
  5524. If you use the shift key and press @kbd{K}, it will keep however many minutes
  5525. you request and then immediately clock out of that task. If you keep all of
  5526. the minutes, this is the same as just clocking out of the current task.
  5527. @item s
  5528. To keep none of the minutes, use @kbd{s} to subtract all the away time from
  5529. the clock, and then check back in from the moment you returned.
  5530. @item S
  5531. To keep none of the minutes and just clock out at the start of the away time,
  5532. use the shift key and press @kbd{S}. Remember that using shift will always
  5533. leave you clocked out, no matter which option you choose.
  5534. @item C
  5535. To cancel the clock altogether, use @kbd{C}. Note that if instead of
  5536. canceling you subtract the away time, and the resulting clock amount is less
  5537. than a minute, the clock will still be canceled rather than clutter up the
  5538. log with an empty entry.
  5539. @end table
  5540. What if you subtracted those away minutes from the current clock, and now
  5541. want to apply them to a new clock? Simply clock in to any task immediately
  5542. after the subtraction. Org will notice that you have subtracted time ``on
  5543. the books'', so to speak, and will ask if you want to apply those minutes to
  5544. the next task you clock in on.
  5545. There is one other instance when this clock resolution magic occurs. Say you
  5546. were clocked in and hacking away, and suddenly your cat chased a mouse who
  5547. scared a hamster that crashed into your UPS's power button! You suddenly
  5548. lose all your buffers, but thanks to auto-save you still have your recent Org
  5549. mode changes, including your last clock in.
  5550. If you restart Emacs and clock into any task, Org will notice that you have a
  5551. dangling clock which was never clocked out from your last session. Using
  5552. that clock's starting time as the beginning of the unaccounted-for period,
  5553. Org will ask how you want to resolve that time. The logic and behavior is
  5554. identical to dealing with away time due to idleness; it is just happening due
  5555. to a recovery event rather than a set amount of idle time.
  5556. You can also check all the files visited by your Org agenda for dangling
  5557. clocks at any time using @kbd{M-x org-resolve-clocks RET} (or @kbd{C-c C-x C-z}).
  5558. @subsubheading Continuous clocking
  5559. @cindex continuous clocking
  5560. @vindex org-clock-continuously
  5561. You may want to start clocking from the time when you clocked out the
  5562. previous task. To enable this systematically, set @code{org-clock-continuously}
  5563. to @code{t}. Each time you clock in, Org retrieves the clock-out time of the
  5564. last clocked entry for this session, and start the new clock from there.
  5565. If you only want this from time to time, use three universal prefix arguments
  5566. with @code{org-clock-in} and two @kbd{C-u C-u} with @code{org-clock-in-last}.

  5572. If you want to plan your work in a very detailed way, or if you need to
  5573. produce offers with quotations of the estimated work effort, you may want to
  5574. assign effort estimates to entries. If you are also clocking your work, you
  5575. may later want to compare the planned effort with the actual working time, a
  5576. great way to improve planning estimates. Effort estimates are stored in a
  5577. special property @samp{Effort}@footnote{You may change the property being
  5578. used with the variable @code{org-effort-property}.}. You can set the effort
  5579. for an entry with the following commands:
  5580. @table @kbd
  5581. @orgcmd{C-c C-x e,org-set-effort}
  5582. Set the effort estimate for the current entry. With a numeric prefix
  5583. argument, set it to the Nth allowed value (see below). This command is also
  5584. accessible from the agenda with the @kbd{e} key.
  5585. @orgcmd{C-c C-x C-e,org-clock-modify-effort-estimate}
  5586. Modify the effort estimate of the item currently being clocked.
  5587. @end table
  5588. Clearly the best way to work with effort estimates is through column view
  5589. (@pxref{Column view}). You should start by setting up discrete values for
  5590. effort estimates, and a @code{COLUMNS} format that displays these values
  5591. together with clock sums (if you want to clock your time). For a specific
  5592. buffer you can use
  5593. @example
  5594. #+PROPERTY: Effort_ALL 0 0:10 0:30 1:00 2:00 3:00 4:00 5:00 6:00 7:00

  5597. @noindent
  5598. @vindex org-global-properties
  5599. @vindex org-columns-default-format
  5600. or, even better, you can set up these values globally by customizing the
  5601. variables @code{org-global-properties} and @code{org-columns-default-format}.
  5602. In particular if you want to use this setup also in the agenda, a global
  5603. setup may be advised.
  5604. The way to assign estimates to individual items is then to switch to column
  5605. mode, and to use @kbd{S-@key{right}} and @kbd{S-@key{left}} to change the
  5606. value. The values you enter will immediately be summed up in the hierarchy.
  5607. In the column next to it, any clocked time will be displayed.
  5608. @vindex org-agenda-columns-add-appointments-to-effort-sum
  5609. If you switch to column view in the daily/weekly agenda, the effort column
  5610. will summarize the estimated work effort for each day@footnote{Please note
  5611. the pitfalls of summing hierarchical data in a flat list (@pxref{Agenda
  5612. column view}).}, and you can use this to find space in your schedule. To get
  5613. an overview of the entire part of the day that is committed, you can set the
  5614. option @code{org-agenda-columns-add-appointments-to-effort-sum}. The
  5615. appointments on a day that take place over a specified time interval will
  5616. then also be added to the load estimate of the day.
  5617. Effort estimates can be used in secondary agenda filtering that is triggered
  5618. with the @kbd{/} key in the agenda (@pxref{Agenda commands}). If you have
  5619. these estimates defined consistently, two or three key presses will narrow
  5620. down the list to stuff that fits into an available time slot.

  5689. Org's method for capturing new items is heavily inspired by John Wiegley
  5690. excellent remember package. Up to version 6.36 Org used a special setup
  5691. for @file{remember.el}. @file{org-remember.el} is still part of Org mode for
  5692. backward compatibility with existing setups. You can find the documentation
  5693. for org-remember at @url{http://orgmode.org/org-remember.pdf}.
  5694. The new capturing setup described here is preferred and should be used by new
  5695. users. To convert your @code{org-remember-templates}, run the command
  5696. @example
  5697. @kbd{M-x org-capture-import-remember-templates @key{RET}}
  5698. @end example
  5699. @noindent and then customize the new variable with @kbd{M-x
  5700. customize-variable org-capture-templates}, check the result, and save the
  5701. customization. You can then use both remember and capture until
  5702. you are familiar with the new mechanism.
  5703. Capture lets you quickly store notes with little interruption of your work
  5704. flow. The basic process of capturing is very similar to remember, but Org
  5705. does enhance it with templates and more.

  5713. The following customization sets a default target file for notes, and defines
  5714. a global key@footnote{Please select your own key, @kbd{C-c c} is only a
  5715. suggestion.} for capturing new material.
  5716. @vindex org-default-notes-file
  5717. @example

  5725. Call the command @code{org-capture}. Note that this keybinding is global and
  5726. not active by default - you need to install it. If you have templates
  5727. @cindex date tree
  5728. defined @pxref{Capture templates}, it will offer these templates for
  5729. selection or use a new Org outline node as the default template. It will
  5730. insert the template into the target file and switch to an indirect buffer
  5731. narrowed to this new node. You may then insert the information you want.
  5732. @orgcmd{C-c C-c,org-capture-finalize}
  5733. Once you have finished entering information into the capture buffer, @kbd{C-c
  5734. C-c} will return you to the window configuration before the capture process,
  5735. so that you can resume your work without further distraction. When called
  5736. with a prefix arg, finalize and then jump to the captured item.
  5737. @orgcmd{C-c C-w,org-capture-refile}
  5738. Finalize the capture process by refiling (@pxref{Refiling notes}) the note to
  5739. a different place. Please
