I knew there must be a simple way, it seemed such an obvious thing
to want to do. But I couldn't find anything about using the label
as an index in any of my Tk/Tkinter books (and I have 6 covering
Tkinter and 2 covering Tcl/Tk!)
I got numerical indices and symbolic ones like "first" and "last"
but no mention of using the label string (and especially not a
partial string pattern).

And this makes much more sense now, I couldn't fathom out what
menu.index(index)
meant!
Thanks so much.
