As someone who uses emacs purely for clojure/lisp and vim for everything else, the biggest feature for me is the fact that this will be the first version of emacs to support menus in <i>terminal mode</i>. So for all the commands you don't remember, a menu is now a click or F10 away. To quote,<p>"Emacs now supports menus on text-mode terminals. If the terminal supports a mouse, clicking on the menu bar, or on sensitive portions of the mode line or header line, will drop down the menu defined at that position."<p>More at: <a href="http://www.masteringemacs.org/article/whats-new-in-emacs-24-4" rel="nofollow">http://www.masteringemacs.org/article/whats-new-in-emacs-24-...</a>
