Just a quick set of keyboard shortcuts used for http://www.twitch.tv/twitchplayspokemon

twitchplayspokemon-controller.js

var a = {
		"37": "left",
		"38": "up",
		"39": "right",
		"40": "down",
		"65": "a",
		"66": "b"
	};
$(document).on('keypress', function(e) {
	if(a[e.which])
		$('#chat_text_input').val(a[e.which]);
 
	$('#chat_speak').click();
	return false;
});
