Map arrow key as action

Discussion & Questions
1

Is it possible to use an arrow key as an action? I would like alt-i (and j and k and l) to be mapped to the arrow keys, so that I don't have to move my lazy arm over to the physical arrow keys. I can't seem to find the arrow keys in the action lists, though - are they there?

Thanks.

Figured it out - I just needed to record myself hitting the arrow key as the action.
