English (Great Britain) (I suspect the same layout as Stephen_SE9 )
I have changed to US layout but that didn’t resolve it. The machine has the Lenovo “keyboard manager” which may be having some impact but I went to the online website to see what keys are being pressed and it sort of confirms that the keypresses are correct despite the keyboard manager
Unfortunately either Alt key doesn’t engage the track removal. The keyboard manager allows for switching between the CTRL and Fn keys (so CTRL can act as the Function key, I have it off and let the Fn key work as it should, my preference)
I’ve added a Bluetooth keyboard but obviously the OS will probably still control input.
