I recently acquired a MS Surface Ergonomic Keyboard. Its a great device for everything other than a Fn lock key that is awkwardly placed between the CTRL and OPTION/WINDOWS key.
I've looked at the keyboard viewer to see what input is being communicated so i might try and override it in Karibener Elements - but the Keyboard Viewer is not showing any key inputs.
How do i find what key is being triggered and disable it?
Note: The 'Fn' key is stateful like a caps lock key.
