This is the official manual for the latest Org-mode release.
You can insert and follow links that have Org syntax not only in Org, but in any Emacs buffer. For this, you should create two global commands, like this (please select suitable global keys yourself):
(global-set-key "\C-c L" 'org-insert-link-global) (global-set-key "\C-c o" 'org-open-at-point-global)
