HP BOOK XE3 manual Using Fn Hot Keys, Effect

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 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.
