Can you explain how to use "Shift" function? When I assign shift to a toggle switch, and configure buttons to use Shift 1, both unshifted and shifted buttons activate.
Yes it is right by buttons intergnal politics: "button 1" work only from "hw.button 1" without any other conditions; "button 9" work with "hw.button 1"(main) + "hw.button 13"(shift);
so you need switch shift with 3 positions "on-off-on" and add second shift to "button 1".
