Toshiba LX830 - Manual (Page 45)

The keyboard battery icon will keep the previous status in any one of
the following situations:
The computer is turned on or restarted
No batteries placed in the keyboard or the batteries are
exhausted
The keyboard is turned off
Function keys: F1 … F12
The function keys (not to be confused with the special FN key) are the
seven keys at the top of your keyboard - these keys function differently
from other keys.
F1 through F12 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.
Soft keys: FN key combinations
The FN (function) is used in combination with other keys to form soft keys.
Soft keys are key combinations that enable, disable or configure specific
features.
Please note that some software may disable or interfere with soft-key
operations, and that the soft-key settings are not restored when the
computer returns from Sleep Mode.
Hot key functions
Hot key functions let you enable or disable certain features of the
computer. The Hot key functions can be performed using either the Hot
Key Cards or by pressing the associated Hot keys.
You can configure the Function Keys Mode by selecting the "Special
function mode" or "Standard F1-F12 mode". Please refer to the
HW Setup
section in Chapter 4, Utilities & Advanced Usage.
