   others alone.

        Only one item can be selected for this menu.

        Display the item descriptions when the menu is posted.

        Display the menu in row-major order.

        Ignore the case when pattern-matching.

        Move the cursor to within the item name while pattern-matching.

        Don't  wrap  around  next-item  and previous-item, requests to the
        other end of the menu.

        If user clicks with  the  mouse  and  it  does  not  fall  on  the
        currently  active menu, push KEY_MOUSE and the MEVENT data back on
        the queue to allow processing  in  another  part  of  the  calling

   supported on Version 7 or BSD versions.
