Touchpad Basics

The following teaches 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 beneath 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) buton to mimic your cursor pressing on the right scroll bar of Windows

applications.

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.

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.

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.

Lock Key Description

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

are in uppercase.

Num 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.

Scroll Lock

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.
