#105772 — Another Key Binding Question

I use some key bindings in my program.  They are declared
like this:

        root.bind("<Alt_L>" + "q", quit)
        root.bind("<Alt_R>" + "q", quit)
        root.bind("<Alt_L>" + "Q", quit)
        root.bind("<Alt_R>" + "Q", quit)

The above binds both Alt keys with upper and lower case 'q'.
Is there a way to combine the statements above into one
statement?

Try this:

     root.bind("<Alt-q>", quit)
     root.bind("<Alt-Lock-Q>", quit)

The first is for either "Alt" key plus the "Q" key and Caps Lock turned off.

The second is for either "Alt" key plus the "Q" key and Caps Lock turned on.

Works perfectly.

Also works, however, I discovered if I leave out 'Lock' it
still works with caps on.  It also works with caps off while
holding either Shift key and hitting Alt-q.  I tested it with
Python 2.7 and 3.4.

Well at least I can cut the number of lines down to two per
binding like this:

        root.bind("<Alt-q>", quit)
        root.bind("<Alt-Q>", quit)

Once again I am in your debt.  Thank you.
