Touchpad
The build-in touchpad is a PS/2 compatible pointing device that senses movement on its surface. 
The cursor responds to your finger movements on the touchpad. In addition, the two click buttons provide 
the same functionality as a computer mouse, while the scroll key enables easy up and down scrolling in
documents and web pages.
The touchpad is located in the middle of the palm rest area, providing maximum comfort and efficiency.
Touchpad Basics
Use the touchpad as follows:
TSlide your finger over the surface of the touchpad to control the movement of the cursor. Tap the
                     touchpad to perform selection and execution functions. 
TPress the left (1) and right (3) buttons to perform selection and execution functions, just as you
                     would use the buttons on a computer mouse.
