shortcut                                     (Assignable)

        Contains an optional numeric inkey value indicating the key that
        activates the menu selection.  The default is 0.  Shortcut keys are
        available only for menu items on a PopUpMenu.  TopBarMenu items
        cannot have shortcut keys associated with them.

        The shortcut key name automatically appears to the right of the
        MenuItem:caption.  Unlike with an accelerator key, the menu need not
        be open for the shortcut key to be active.
