I can never find a straight up answer to this question but can you answer it like this.

Negative Button = bla
Positive Button = bla
Alt
//then the rest of it

this is the script line that is using it if you're wondering 
if (Input.GetAxis("MouseScrollWheel") >= 0.2 && ArrayNum <= MaxArrayNum)

alt text

thanks in advance

this will give some idea

var e = Event.current;
if (e.type == EventType.ScrollWheel) {
    if (e.delta.y < 0)
        print("Scrolling Down");
    else
        print("Scrolling Up");
}
