On some keyboards, the multimedia function keys are overlaid with the F
keys. This property enables clients to switch the primary mode of these F
keys between function keys and multimedia keys.
Some keyboards provide an Fn key to toggle between the modes. This is
hardware-specific and may or may not work on any given keyboard device.
The current imlementation is only hooked up to apple keyboards.
The kernel provides a tweak to enable/disable.
/sys/module/hid_apple/parameters/fnmode
0 .. keyboard sends Fx keys, Fn disabled
1 .. keyboard sends multimedia keys, Fn toggles to function keys
2 .. keyboard sends function keys, Fn toggles to multimedia keys
If fnmode is on 0, we force it to 2.
