Using the Keyboard 
The keyboard has full-sized keys and an embedded keypad, separate cursor keys, two Windows keys 
and twelve function keys.
Lock keys and embedded numeric keypad
The keyboard has three lock keys which you can toggle on and off.
 
 
The computer features three lock keys, each with its own status indicator light.
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 KeyDescription
Caps Lock When Caps Lock is on, all alphabetic characters are typed 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.
