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 on the surface of the touchpad.  The central location on the palmrest 
provides optimum comfort and support.
Touchpad Basics
The following items teach you how to use the touchpad:
!Move your finger across the touchpad to move the cursor. 
!Press the left and right buttons located on the edge of the touchpad to do selection and execution 
functions. These two buttons are similar to the left and right buttons on a mouse. Tapping on the 
touchpad produces similar results.
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.
