If "::tk::MenuNextMenuon" function is available  your Tcl/Tk library, you will be able to move to the next menu by Tab key on the posted menu, or the previous menu by Alt + Tab key.
Please read the sample source, and check how to override default configure options of menu entries on a menu_spec. Maybe, on windows, this menubar does not work properly about keyboard shortcuts. Then, please use "menu" option of root/toplevel widget (see sample/menubar3.rb).')
