Using Fn Hot Keys
The combination of the Fn key plus another key creates a
hot key
—a shortcut key sequence—for
various system controls. To use a hot key, press
and hold
Fn, press the appropriate second key, then
release both keys.
External PS/2 keyboards support only Fn+F5, Fn+F7, and Fn+F12. To use these, press and hold left
CTRL+left ALT, press the appropriate second key, then release both keys.
External USB keyboards do not support Fn hot keys.
