28 | ;; This package maintains a menu for visiting files that were operated | |
29 | ;; on recently. When enabled a new "Open Recent" submenu is displayed | |
30 | ;; in the "Files" menu. The recent files list is automatically saved | |
31 | ;; across Emacs sessions. You can customize the number of recent | |
32 | ;; files displayed, the location of the menu and others options (see | |
33 | ;; the source code for details). To install and use, put the file on | |
34 | ;; your Emacs-Lisp load path and add the following into your ~/.emacs | |
35 | ;; startup file: | |
36 | ;; | |
37 | ;; (require 'recentf) | |
