The top row of the keyboard is a capacitive touch panel. The fn mechanical key toggles between the keys F1-F12 and keys for
multimedia control. Releasing the fn key switches back to the previous mode.
Pressing the fn key and the esc key locks the "mode" of the capacitive touch panel. If the computer restarts, the default mode
is the last mode set by the user before the computer is restarted.
The fn key is also used with selected keys on the keyboard to invoke other secondary functions.
