Acer Aspire E 17 - Using the Precision Touchpad

Using the Precision Touchpad - 17
USING THE PRECISION TOUCHPAD
The touchpad controls the arrow (or 'cursor') on the screen. As you
slide your finger across the touchpad, the cursor will follow this
movement. The Precision Touchpad (PTP) is designed to provide a
more uniform, smooth, and accurate touchpad experience. Many
applications support precision touchpad gestures that use one or
more fingers, however, some gestures may not be supported by the
specific application or program you are using.
