COMPONENTS AND FUNCTIONS

Keyboard

The keyboard is functionally equivalent to a full size desktop keyboard. A sample key layout is shown below.

The Numeric Keypad

The numeric keypad functions like an electronic calculator. It is embedded in the main keyboard, with the numeric figures printed on the upper right of their respective keys. The keypad has keys for the digits 0 through 9, the decimal point ( . ), addition ( + ), subtraction ( - ), multiplication ( * ), and division ( / ).

To activate the keypad, press the Num Lock key. The 15 keys shown in the figure switch from alphabetic keys to numeric keys. Press Num Lock again switches the keys back to alphabetic.
