Examples:
- Open cover while button is pressed, stop on release
- repeat action periodically (volume up every 0.5s) until released.
For point 1… One might say “change the position percentage”, but it won’t work for covers without position sensing. I want to fine tune a position in real time but can be awkward to keep switch between Open/Stop buttons.
For point 2… One might not want a sudden volume change and/or not know the exact volume desired.
