English buttons are similar to the left and right buttons on a mouse.
Tapping on the touchpad produces similar results.
• Use the 4-way scroll (#2) 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: Keep your fingers dry and clean when using the touchpad.
Also keep the touchpad dry and clean. The touchpad is sensitive
to finger movements. Hence, the lighter the touch, the better the
response. Tapping harder will not increase the touchpad’s
responsiveness.
