same as clicking the left button.
• Use the 4-way scroll (3) button to scroll up or down and move left or right
a page. This button mimics your cursor pressing on the right scroll bar of
Windows applications.
Note: When using the touchpad, keep it — and your fingers — dry
and clean. The touchpad is sensitive to finger movement; hence,
the lighter the touch, the better the response. Tapping harder will
not increase the touchpad's responsiveness.
Note: By default, vertical and horizontal scrolling is enabled on
your touchpad. It can be disabled under Mouse settings in
Windows Control Panel.
