Acer 330 - Manual (Page 20)

20 System Introductions
Use the center (2) buttons (top and bottom) to scroll up or down 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 too hard will not increase the touchpad’s
responsiveness.
