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

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