MENU [-C] TITLE|ITEM|SUBITEM|BAR|SUBBAR|END name [action [shortcut]] ...

* The MENU command allows to add gadtools menus to the console window
  ZShell runs in. To use it with OS1.3 you have to get dev/misc/gt34_1.lha
  from Aminet before and install it.
  Because the standard console does not set the NEWLOOKMENUS flag, menus
  will have nasty colors under OS3.0+. Get util/cdity/MagicMenu_1_29.lha
  from Aminet and use ForceNewLook (included there, less than 1KB big)
  to fix this.
* "MENU -C" removes the current menu strip from the window and clears it
  in memory.
* "MENU END" attaches the current menu strip to the window.
  You can use it to refresh the menu, too.
  After using this you can add some more things and use MENU END again.
* See the examples in the included ZStart.OSx files for more. ;-)
* If no action is specified, the name will be the action.
  Actions can be defined the same way as function key definitions.
  See  ALIAS  and  ECHO  for more.
* Below OS3.0, only a single lowercase character can be used as a
  shortcut. This shortcut will be activated, if you press Right-Amiga
  and the given key.
  Under OS3.0+ you can use several characters, but then shortcuts will
  not work automatically.
