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:
T
Move your finger across the touchpad (2) to move the cursor.
T
Press the left (1) and right (4) buttons located on the edge of the touchpad to perform selection
and execution functions. These two buttons are similar to the left and right buttons on a mouse.
Tapping on the touchpad is the same as clicking the left button.
T
Use the 4-way scroll (3) button to scroll up or down and move left or right a page. This button
