  Sorry, I meant to type:

         C-c g-

   which I have bound to "magit-status":

(defadvice magit-status (around magit-fullscreen activate)
  (window-configuration-to-register :magit-fullscreen)
  ad-do-it
  (delete-other-windows))
(global-set-key "\C-c\g" 'magit-status)

  I'll try to get a minimal configuration.

  Thanks.
