I can turn the touchpad off in the mouse settings, but two things won't work:
The "disable while typing" option
The standard on/off button for the touch pad won't work (it's the one with the little touchpad symbol crossed off, on the F6 key). I've tried any of the following combinations:
- Alt+F6
- Fn+F6
- Ctrl+F6
- Super+F6
- Shift+F6.
Almost all the other keys of that kind work, like brightness control, volume control, Wifi toggle, but this one and the mic off and camera off won't work.
