Action Button Keystrokes take MouseOver and MouseOff

Pretty sure this isn’t in Vassalengine yet, so thought I’d ask for opinions.

For the Action Button trait, are there plans to allow “keystrokes” with the mouse, especially MouseOver and MouseOff?

That’ll be cool. I can then make maps clean, popping up detailed information only upon MouseOver.

Not planned, I have added an enhancement request for this idea.
