A Youtube tutorial viewer asked how to use a knob for both up and down movement.
Will post at project file here shortly
The following project has 2 knobs and a button,
One knob moves the mouse up or down. Another knob moves it left or right. If you push the button while turning one of the knobs it will allow fine tuning (smaller movement).
