  The menu bar at the top of the SCA application windows contain pull-down
  menus.  You use pull-down menus to select items (enter commands).  To display
  a pull-down menu, position the pointer on a menu name in the menu bar and
  press MB1.  To choose an item from the menu, position the pointer on the
  desired item and press MB1.
