4.5 Using links outside Org
===========================
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)
