I misunderstood the question, originally. I looked into it. You’re right. Input Key Selector does not respond to mouse wheel input. Odd. Must be an oversight. I borrowed some code from [Mathew Wadstein][1] and came up with a work-around. It’s based on the idea that we’re not going to be using all our keys in-game. So, pick two unused keys and remap (intercept) them to your mouse wheel buttons during the OnSelectKey event.
