Chapter 5 The Keyboard; Function Keys: F1; Soft Keys: Fn Key Combinations - Toshiba Satellite P750 Series User Manual

The Keyboard
The computer's keyboard layouts are compatible with a 104/105-key
enhanced keyboard - by pressing some keys in combination, all of the
104/105-key enhanced keyboard functions can be performed on the
computer.
The number of keys available on your keyboard will depend on which
country/region your computer is configured for, with keyboards being
available for numerous languages.
In use there are six different types of keys, specifically typewriter keys,
function keys, soft keys, Hot keys, Windows special keys and the keypad
overlay.
Never remove the key caps on your keyboard. Doing so could cause
damage to the parts under the key caps.
Function keys: F1 ... F9
The function keys (not to be confused with the special FN key) are the nine
keys at the top of your keyboard - these keys function differently from other
keys.
F1 through F9 are called function keys because they execute programmed
functions when pressed and, when used in combination with the FN key,
those keys marked with icons also execute specific functions on the
computer. Please refer to the section,
this chapter for further information, taking care to note that the function
executed by individual keys will depend on the software you are using.

Soft keys: FN key combinations

The FN (function) is unique to TOSHIBA computers and is used in
combination with other keys to form soft keys. Soft keys are key
combinations that enable, disable or configure specific features.
