Can you have more than one layer active at a time?

This will toggle them independently, meaning both layers can be active at the same time and activating one does not deactivate the other, which might not be what you want.

This does not work when one of the inputs is a GPIO

I have not yet found an example which shows how to have more than one layer active. Very disappointing.

All I want to do is slow the mouse cursor down when button6 is held on my trackball, it seems a trivial ambition.
