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 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

connect an external keypad.
