This is great, because for many commands that has a left/right, up/down, or previous/next operations, such as page up/down, cursor word left/right, next/prev app/window/workspace, etc, the most efficient physical control of them is by a wheel or knob. It allows you to control repetition speed, and easily reverse direction.
