{
      Simply pass a number (1-3) through it:
         1 -- Switches to next window
         2 -- Pops up the Alt menu
              ^^^^^^^^^^^^^^^^^^^^ this is what you want
         3 -- Close the current window

      I don't know about Alt-H though.. I know that if you used ReadKey
      you'd have to read it twice -- once for the #0 (tells you that
      it is an extended code) -- again for the extended code (35=Alt-H).

      Hope this helps!  Good luck.
