yes. CC-ing benjamin, he's done work on the type covers before and knows the
current state.

as for tap-to-click and scrolling: the device just looks like a normal mouse
with a scroll wheel. tapping is implemented in the firmware, we don't have
access to it. here too we'd need the kernel to support this properly and expose
it as a touchpad device.

We can put a quickfix in for the F23 though. In libinput's
evdev_pre_configure_model_quirks() put in a call to 

   libevdev_disable_event_code(device->evdev, EV_KEY, KEY_F23);

and see if that has any side-effects. as you noticed, F23 is used for touchpad
disabling, so let's see what happens if we just completely filter this out.
