Disable the FN key on Microsoft media keyboard
I have a Microsoft all-in-one media keyboard. Is there any way to lock/remove/disable the FN key?
Try pressing Fn + Caps Lock to disable the fn-lock, see this Microsoft support page for more information:
Enabling FN Lock on the All in One Media Keyboard
To enable FN Lock on the All in One Media Keyboard, press the FN key, and the Caps Lock key at the same time. To disable FN Lock, press the FN key, and the Caps Lock key at the same time again.
Try long pressing the function key...It worked for me with my Microsoft designer keyboard. The light on the Fn key turns on....
