Pull-down Menus

  Pull-down menus are the most common type of DECwindows
  menu.  The titles of pull-down menus appear in the menu
  bar of a window, which is directly under the title bar.

  To choose an item from a pull-down menu:

  1.  On the menu bar, point to the name of the menu you
      want to display.

  2.  Press and hold MB1.

  3.  While holding MB1, drag to the menu item you want.

  4.  Release MB1.

  If you change your mind while looking at a pull-down menu,
  drag the pointer outside the menu and release MB1.  The
  menu disappears and no action is taken.

  Some pull-down menus have submenus.  If a pull-down
  menu has a submenu, the submenu icon (an arrow) appears
  to the right of the pull-down menu.
