    All I want to know is why the heck I can't un-press a button I pressed by accident. This should be very simple. Press once to turn the button on, press again to turn it off.

    Or I guess you could do long-press to turn off or something if you're worried about confusing people, but I really don't think that should be necessary. We know how toggles work. The button lights up when it's on.

      The most common control circuit has the button triggering a relay which then powers its own trigger until the circuit is interrupted elsewhere; this isn't compatible with the same button cancelling the call.

        On the pop-out controls I mentioned in a sibling comment, the relay is the button, and you can pull it out to cancel.
