Chapter 113 Lock Keys The keyboard has three lock keys which you can toggle on and off. NOTE: To access the Num Lock and Scroll Lock functions, hold the Fn key down while pressing the F11 and F12 keys respectively. Lock KeyDescription Caps Lock When Caps Lock is on, all alphabetic characters typed are in uppercase. Num Lock (Fn-F11) When Num Lock is on, the embedded keypad is in numeric mode. The keys function as a calculator (complete with the arithmetic operators +, -, *, and /). Use this mode when you need to do a lot of numeric data entry. A better solution would be to connect an external keypad. Scroll Lock (Fn-F12) When Scroll Lock is on, the screen moves one line up or down when you press the up or down arrow keys respectively. Scroll Lock does not work with some applications.

To simplify the keyboard legend, cursor-control key symbols are not printed on the keys.

18Chapter 1 Touchpad The built-in touchpad is a PS/2-compatible 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. NOTE: When using an external USB or serial mouse, you can press Fn-F7 to disable the touchpad. If you are using an external PS/2 mouse, the touchpad is automatically disabled . Touchpad Basics The following items teach you how to use the touchpad: TMove your finger across the touchpad to move the cursor. TPress the left (1) and right (3) 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. TUse the 4-way scroll (2) button (top/bottom/left and right) to scroll a page up, down, left or right. This button mimics your cursor pressing on the vertical and horizontal scroll bars of Windows applications.
Chapter 119 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.
