* Undo-tree. (http://www.emacswiki.org/emacs/UndoTree) Makes emacs undo useful.

This has been one of the most useful functions I've added to my .emacs:

   (defun xsteve-ido-choose-from-recentf ()
     "Use ido to select a recently opened file from the `recentf-list'"
     (interactive)
     (let ((home (expand-file-name (getenv "HOME"))))
       (find-file
        (ido-completing-read "Recentf open: "
                             (mapcar (lambda (path)
                                       (replace-regexp-in-string home "~" path))
                                     recentf-list)
                             nil t))))

   (global-set-key [(meta f11)] 'xsteve-ido-choose-from-recentf)
