Google Translate: Sorry, but I can not understand for serving the trigger event. Please, you can explain it to me?
Okay, the "Trigger once while true" means it only happens once when the button is not being pressed. I've inverted the "control is down" to make it mean "control is up"
But, whenever a layout starts, the "control is up" will trigger once, but never again until the control is next pushed down and released.
