Extend Menu... Available Entries
  Lists the EVE commands (menu items) available for menus.
  Steps:
     1.  To enter or delete commands in the list, do either of the
         following:
         o  Click M1 on a command in the Available Entries list.
            (To scroll the list, use the scroll bar at the right.)
         o  Type the EVE command on the line just below the list.
     2.  Optionally, type a label for the menu entry. For example, if you
         add the SHOW BUFFERS command to a menu, you can have it appear as
         Buffer List instead.
     3.  To add the command ...... click on ENTER.
         To delete the command ... click on DELETE.
  Entering or deleting a command in the Available Entries list does not by
  itself change the contents of any pull-down or pop-up menus, but only
  changes which commands appear in the list.
