What is the framerJS method to know if a finger is being held down anywhere on the screen? Like a scroll event, but just for the finger touching the screen.

Canvas.onLongPress ->
print 'pressing'

Layer.on Events.touchStart(Events, Layer)
Layer.on Events.touchMoved(Events, Layer)
Layer.on Events.touchEnd(Events, Layer)

myInterval = utils.interval 60 ->
//Do Stuff

layerA.onMouseUp ->
