This is the official manual for the latest Org-mode release.
Since Emacs 22.2, files with the .org extension use Org mode by default. If you are using an earlier version of Emacs, add this line to your .emacs file:
(add-to-list 'auto-mode-alist '("\\.org\\'" . org-mode))
Org mode buffers need font-lock to be turned on: this is the default in Emacs1.
There are compatibility issues between Org mode and some other Elisp packages, please take the time to check the list (see Conflicts).
The four Org commands org-store-link, org-capture, org-agenda, and org-iswitchb should be accessible through global keys (i.e., anywhere in Emacs, not just in Org buffers). Here are suggested bindings for these keys, please modify the keys to your own liking.
(global-set-key "\C-cl" 'org-store-link) (global-set-key "\C-ca" 'org-agenda) (global-set-key "\C-cc" 'org-capture) (global-set-key "\C-cb" 'org-iswitchb)
To turn on Org mode in a file that does not have the extension .org, make the first line of a file look like this:
MY PROJECTS -*- mode: org; -*-
which will select Org mode for this buffer no matter what
the file's name is. See also the variable
Many commands in Org work on the region if the region is active. To make
use of this, you need to have
zmacs-regions in XEmacs) turned on. In Emacs 23 this is the default,
in Emacs 22 you need to do this yourself with
If you do not like
transient-mark-mode, you can create an
active region by using the mouse to select a region, or pressing
C-<SPC> twice before moving the cursor.
 If you don't use font-lock globally, turn it on in Org buffer
(add-hook 'org-mode-hook 'turn-on-font-lock)
