Updating selections to use arrow keys?

[Zalanshah64]

Okay, so as painful as the process of mathing out each square and it's colors was, there's something that just feels good about being able to use the arrow keys to move. I think maybe making all menus use arrow keys would be a really cool feature, though I'm unsure of whether or not that'd be something people would necessarily want, since it's definitely slower.

Maybe keeping the current options, but adding arrow key functionality could be the way to go?
