Toshiba Satellite L855 - Manual (Page 39)

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 different types of keys, specifically typewriter keys,
function keys, soft keys, Hot keys and Windows special keys.
Never remove the key caps on your keyboard. Doing so could cause
damage to the parts under the key caps.

CAPS LOCK This indicator glows green when letter keys are
locked into their uppercase format.

entry.
Function keys: F1 … F12
The function keys (not to be confused with the special FN key) are the
twelve 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.
