Keyboard/touchpad Middle Button - How To Use Or Switch Functions? Model:Qumax Ione Scorpius-P6-USB
My Scorpius-P6 USB keyboard with built-in touchpad has a user's guide written in an Asian language. The touchpad has three buttons. I am sure the middle button is useful for scrolling, but the feature is not intuitive. I cannot figure what I did (once) to access the pointer scrolling feature, but with my fumbling, it did not last long enough to let me know. What are the possible features of the middle button on this model, and how do I control them or change them?
