Function Keys
On the top row of the keys are the function keys: F1 to F12. These are multi-
purpose keys that perform functions defined by individual programs.
Fn Key
The Fn key, at the lower left corner of the keyboard, is used with another
key to perform the alternative function of a key. To perform a desired
function, first press and hold Fn, then press the other key.
Hot Keys
Hot keys refer to a combination of keys that can be pressed any time to
activate special functions of the computer. Most hot keys operate in a cyclic
way. Each time a hot key combination is pressed, it shifts the corresponding
function to the other or next choice.
You can easily identify the hot keys with the icons imprinted on the keytop.
The hot keys are described next.
