Emacs 24 with fullscreen? Is there a way to use Emacs 24 in fullscreen mode? The Emacs wiki seems to imply that it has been disabled, but that there are some workarounds / patches. 

It doesn't have to be "true" full screen, but I like to work without having the OS menubar  on the top and launcher at the bottom.

In the end, it is not clear how I can implement these patches or workarounds, which one I should use and / or if I should just install emacs &lt;= 23.3.

My current .emacs includes the following (which allows me to use F11 to toggle fullscreen under Emacs 23 in Linux)

(defun fullscreen ()
 (interactive)
 (set-frame-parameter nil 'fullscreen
              (if (frame-parameter nil 'fullscreen) nil 'fullboth))
(progn
  (if (fboundp 'tool-bar-mode) (tool-bar-mode -1))  ;; no toolbar
  (menu-bar-mode -1) ;;no menubar
  (scroll-bar-mode -1) ;; no scroll bar
  )
)

(global-set-key [f11] 'fullscreen)
If you use Yamamoto Mitsuharu's emacs-mac-port then true full-screen "Just Works" (and much else too).  No need for any patches or workarounds.  At least, this is true for me on Mountain Lion.  YMMV on earlier OS versions.
