Automatically add an appointment when clocking in a task

:;; Make sure you have a sensible value for `appt-message-warning-time' :(defvar bzg-org-clock-in-appt-delay 100

 "Number of minutes for setting an appointment by clocking-in")

This function let's you add an appointment for the current entry. This can be useful when you need a reminder.

:(defun bzg-org-clock-in-add-appt (&optional n)

 "Add an appointment for the Org entry at point in N minutes."
 (interactive)
 (save-excursion
   (org-back-to-heading t)
   (looking-at org-complex-heading-regexp)
   (let* ((msg (match-string-no-properties 4))
   (ct-time (decode-time))
   (appt-min (+ (cadr ct-time)
		(or n bzg-org-clock-in-appt-delay)))
   (appt-time ; define the time for the appointment
    (progn (setf (cadr ct-time) appt-min) ct-time)))
     (appt-add (format-time-string
	 "%H:%M" (apply 'encode-time appt-time)) msg)
     (if (interactive-p) (message "New appointment for %s" msg)))))

You can advise org-clock-in so that C-c C-x C-i will automatically add an appointment:

:(defadvice org-clock-in (after org-clock-in-add-appt activate)

 "Add an appointment when clocking a task in."
 (bzg-org-clock-in-add-appt))

You may also want to delete the associated appointment when clocking out. This function does this:

:(defun bzg-org-clock-out-delete-appt nil

 "When clocking out, delete any associated appointment."
 (interactive)
 (save-excursion
   (org-back-to-heading t)
   (looking-at org-complex-heading-regexp)
   (let* ((msg (match-string-no-properties 4)))
     (setq appt-time-msg-list
    (delete nil
	    (mapcar
	     (lambda (appt)
	       (if (not (string-match (regexp-quote msg)
				      (cadr appt))) appt))
	     appt-time-msg-list)))
     (appt-check))))

And here is the advice for org-clock-out (C-c C-x C-o)

:(defadvice org-clock-out (before org-clock-out-delete-appt activate)

 "Delete an appointment when clocking a task out."
 (bzg-org-clock-out-delete-appt))

*IMPORTANT*: You can add appointment by clocking in in both an =org-mode= and an org-agenda-mode buffer. But clocking out from agenda buffer with the advice above will bring an error.

Use Org-mode with Screen [Andrew Hyatt]

"The general idea is that you start a task in which all the work will take place in a shell. This usually is not a leaf-task for me, but usually the parent of a leaf task. From a task in your org-file, M-x ash-org-screen will prompt for the name of a session. Give it a name, and it will insert a link. Open the link at any time to go the screen session containing your work!"

 "Open the screen with the specified name in the window"
