on.'''arrowKey'''() is an event handler. <br> 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).<br>
== Example ==
<source lang="lua">
msg = ""
function on.paint(gc)
gc:drawString(msg, 10, 10, "top")
end
function on.arrowKey(key)
msg = "Key " .. key
platform.window:invalidate()
end
</source>
