I'm jumping on this thread since it's a similar request: I'd like a combination of inputs to do something. Particularly, it's such a small detail but it bothers me that this is the only program I have that I can't close with Alt+F4. I set it to exit to "F4", but I know for a fact that I don't need to press Alt+F4 to close it, just F4, so that bothers my OCD haha...
And also sometimes I pick up the mouse and instinctively rotate the wheel expecting it to do something, but then I remember there's no input called "WheelUp" / "WheelDown"... so that would be a nice addition I think.
