Touchpad
The built-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 4-way scrolling in documents and web 
pages.
The touchpad is located in the middle of the palm rest area, providing maximum comfort efficiency.
Touchpad basics
Use the touchpad as follows:
TSlide your finger over the surface of the touchpad control the movement of the cursor. Tap the 
touchpad to perform selection and execution functions.
TPress the left (1) and right (3) click buttons to perform selection and execution functions, just as 
you would use the buttons on a computer mouse.
TUse the scroll key (2) to scroll through long documents and web pages. Press the top of the key to 
scroll up, bottom to scroll down; left to scroll left, and right to scroll right.
