Gestures
The Quha Zono 2 mouse has a built-in gesture detection to activate
commonly used mouse features.
Pause stops the cursor until the user makes the exit pause gesture.
When scrolling is activated, the cursor is centered and makes a small circle
for indication. During the following 3 seconds, the user moves the cursor
onto the window to be scrolled. The window can then be scrolled by making
up/down movements. Scrolling is ended by making the exit scroll gesture.
Centering places the cursor in the central area of the screen.
