Using the Keyboard
Your computer has a close-to-full-sized keyboard and an embedded numeric keypad, separate cursor, lock, 
function and special 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 key caps. 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 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.
