on.arrowKey() is an event handler.
This handler get called when a arrow key gets pressed. This handler will not be called if you already use other handlers to catch arrow keys (such as on.arrowLeft).

Example[edit]

msg = ""
 
function on.paint(gc)
	gc:drawString(msg, 10, 10, "top")
end
 
function on.arrowKey(key)
	msg = "Key " .. key
	platform.window:invalidate()
end
