Cascading bash menus
I currently have a main menu (using whiptail) and one of the options makes an instance of another menu - sort of cascading fashion.

I like to be able to terminate the current (top) menu and return to the underlying main one.


I was thinking enclosing the main menu in "do... done" block.



I have some issues copying using mouse blocks - it hopelessly breaks the file so I really do not want to try this without having same confidence it will do the job.



Thanks

__________________________________________________________________________________________________________________________________________________

NAME

       tk_menuBar, tk_bindForTraversal - Obsolete support for menu bars

SYNOPSIS

       tk_menuBar frame ?menu menu ...?

       tk_bindForTraversal arg arg ...
_________________________________________________________________

DESCRIPTION

       These  procedures  were used in Tk 3.6 and earlier releases to help manage pulldown menus and to implement keyboard traversal of menus.	In
       Tk 4.0 and later releases they are no longer needed.  Stubs for these procedures have been retained for backward  compatibility,  but  they
       have no effect.	You should remove calls to these procedures from your code, since eventually the procedures will go away.

       From Tk 8.0 onwards, you should instead construct your menubar as a normal menu and then attach it to the toplevel of your choice using the
       -menu option of that widget.

       menu(1T), toplevel(1T)

KEYWORDS

       keyboard traversal, menu, menu bar, post
