It seems you just stuck it here because this is part of the specific device. It is also hardly a feature unique to this device. I'm typing this from a device with the exact same thing (M1 Macbook Pro). Actually, all 3 laptops I have in front of me have the same thing. The other 2 have a Fnlock (Fn+ESC) though. On the M1, it's just a module param which I set as persistent. Though I now wonder if the Fnlock could be implemented on it too. Being able to switch whenever I want would be nice. That would probably have to be in Linux where as these other laptops probably implement this in their EC/firmware? What I'm getting at is controlling changing this in firmware is not a great experience and this should all be common. Rob
