A game (Montezuma’s Revenge) uses multiple numpad keys for jumps – left jump, right jump and straight jump. I’d like to use a single button to map to all three keys, by context: If moving left, the jump button would jump left, etc.

I had several ideas how to do that, but all failed on the fact that I’m unable to attach an action to a button release.
For instance, one possible way would be this: Create a right jump layer for the right jump button, another layer for the left jump button, etc. When right arrow is pressed (to move the character right), it would make the right jump layer visible and thus make the corresponding right jump button accessible. The problem is that I don’t know how to hide the layer again when the right arrow is released.

Is there any way how to achieve the desired result (i.e. have a single button for jumping instead of three separate buttons)?
