Activating Hotkeys
When activating hotkeys, press and hold the first key Fn before pressing the other key in the hotkey 
combination.
Keyboard Ergonomics
Located below the keyboard, the wide and curved palm rest is ergonomically designed to provide you with a 
very comfortable place to rest your hands while you type.
Touchpad
The built-in touchpad is a PS/2-compatible pointing device that senses movement on its surface.  This means 
that the cursor responds as you move your finger on the surface of the touchpad.  The central location on the 
palm rest provides optimum comfort and support.
NOTE: 
When you connect an external PS/2 mouse, the computer automatically disables the internal touchpad.

Touchpad Basics
The following items teach you how to use the touchpad:
1.
Move your finger across the touchpad to move the cursor.
2.
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 too hard will not increase the touchpad’s responsiveness.
