Touch sensors
Your @boardname@ has touch sensors that work like buttons. Instead of saying enter or left as the source button, use a touch sensor block with a sensor name like touch 1.
sensors.touch1.onEvent(ButtonEvent.Pressed, function () {
brick.setStatusLight(StatusLight.Orange);
});
Read about touch sensors and using them as touch buttons.
