[Tkinter] arrow key selection for menu

[knoxvilles_joker]

This works exactly the way I wanted so thanks there. I will just need to tweak the code to work with my splash screen setup but that is no big deal. I will post the code once I get that hashed out.

Thanks a bunch for the help. The grouping took me a bit to wrap my head around as programming is something I can do but I would not say it is something that comes easily or that I am good at. But I will bulldog through the problem and force the issue to a conclusion, even if I annoy some folks in the process, unfortunately.
