Meta Key
          Meta Key and the Sun Keyboard -- File commands can
          be typed with a few keystrokes by using the Meta
          Key in conjunction with the file manager menus.
          On the Sun keyboard, the Meta key is indicated by
          a black diamond on the key cap.  The Meta key
          sequences first select a menu from the file
          manager or program manager.  The key that will
          select a menu is underlined on the menu bar.
          Once selected the menu will open.  Each menu
          option has an underlined  key that will select
          this option.   The keyboard short cuts execute the
          menu options directly without first opening a
          menu.  Because these short cuts are not visible to
          the user, the keyboard accelerators or short cuts,
          Alt+Shift+(), sequences have to be memorized.
          With the Meta key sequences, the user can read the
          alpha key used in conjunction with the Meta key
          directly from the menu bar.
