With the new ALBA keyboard, you do not need to tell your OS whether you prefer the Fkeys to work as multimedia controls, or as regular Fkeys.

The "fn Lock" can be activated [Command + fn] and the Fkeys are used as multimedia keys. And to use the Fkeys as regular F1, F2, etc, just use the Fkeys with the fn modifier. A glance at the fn Lock light tells you which mode you are in.
