NOTE: When using the touchpad, keep it - and your fingers - 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.

Chapter 1 13

Using the Keyboard

The keyboard has full-sized keys and an embedded keypad, separate cursor keys, one Windows key and twelve function keys.

Lock Keys and embedded numeric keypad

The keyboard has three lock keys which you can toggle on and off.

Lock Key Description

Caps Lock When Caps Lock is on, all alphabetic characters typed

are in uppercase.

Num lock

Scroll lock

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.

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.

The embedded numeric keypad functions like a desktop numeric keypad. It is indicated by small characters located on the upper right corner of the keycaps. To simplify the keyboard legend, cursor-control key symbols are not printed on the keys.
