recentf

This package maintains a list of recently opened files and makes it
easy to visit them.  The recent files list is automatically saved
across Emacs sessions.

There are three ways to access recent files:

(1) `M-x recentf-open' prompts for a recently opened file.

(2) When this mode is enabled, a new "Open Recent" submenu is
    displayed in the "File" menu.

(3) `M-x recentf-open-files' lists recently visited files in a
    buffer.

You can customize the number of recent files displayed, the
location of the menu and other options.  Type:

    M-x customize-group RET recentf RET

To enable this package, add this line to your Init file:

    (recentf-mode 1)
