Keyboard
The keyboard features full-size keys with an embedded keypad, separate cursor control keys, two Windows
keys, and twelve function keys.
Special keys
Lock keys
The keyboard has three lock keys which you can toggle on and off.
Lock KeyDescription
Caps LockWhen Caps Lock is on, all alphabetic characters are typed in uppercase.
Num lock
(Fn-F11)
Scroll lock
(Fn-F12)
When Num Lock is on, the embedded numeric keyboard can be used. The keys
function as a calculator (complete with the arithmetic operator +, -, *, 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.
12Chapter 1
Embedded Keypad
The embedded 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.
To use the embedded numeric keys, toggle the Num Lock on by pressing the Fn + F11 keys simultaneously.
With the embedded keypad turned on, the following actions are possible:

+ F (Finds Document)
+ M (Minimizes all windows)
j + + M (Undoes the minimize all windows action)
+ R (Displays the Run... dialog box)
Application keyThis key has the same effect as clicking the right mouse button; it opens the application’s
context menu.

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 efficiency.
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 to scroll a page up, down, left or right. This button mimics your
cursor pressing on the vertical and horizontal scroll bards of Windows applications.
