How to toggle Fn keys on Windows 10

The Windows 10 laptop has Phone or Position keys at the top. They perform two different duties; media control, and general app control. To switch between these functions, users must hold down the Fn key when they press one of these keys.

The Fn key changes the state / function of the Action keys from their primary to their secondary. This key acts as the Shift key ie, it needs to be held down in order to use the secondary function of the Action keys. It does not work as an on / off switch.
