Touchpad
The built-in touchpad is a pointing device that senses movement on its surface. This means the cursor
responds as you move your finger across the surface of the touchpad. The central location on the palmrest
provides optimum comfort and support.

Acer FingerNav 4-way control function (for selected models) to scroll up or down and move left or right a
