Known issues

I took a key codes list on internet and I noticed that it's may not be completely exact (at least on my mac). If you have information about that please contact me
I'll maybe add a key aliases array to have multiple name for a same key (ex: left window key = left cmd key = left win = left cmd).
Conflict with OS/browser shortcuts (don't know if it's really an issue but I prefer to notice it here.)

Demonstrations

Single key

var	dest	=	parseInt($('#demo div').css('left'));
$().shortcut('left arrow', function() {
	dest	=	dest - 10 < 0 ? 0 : dest - 10;
	$('#demo div').stop(true, false).animate({
		left: dest + '%'
	});
	$('#demo div div').text('←');
}, function() {
	$('#demo div div').text('');
});

$().shortcut('right arrow', function() {
	dest	=	dest + 10 > 100 ? 100 : dest + 10;
	$('#demo div').stop(true, false).animate({
		left: dest + '%'
	});
	$('#demo div div').text('→');
}, function() {
	$('#demo div div').text('');
});

Keys combination and namespace

a+z state:: released
a+z,a+e.test2 state:: released

$().shortcut('bind','a+z', function() {
    $('#demo2').css({color: 'red'}).text('pressed');
}, function() {
    $('#demo2').css({color: 'blue'}).text('released');
});
$().shortcut('bind','a+z,a+e.test2', function() {
    $('#demo3').css({color: 'red'}).text('pressed');
}, function() {
    $('#demo3').css({color: 'blue'}).text('released');
});

Get pressed shortcut

$(document).bind('keydown keyup focus blur',function(e){
	$('#demo4').val($().shortcut.toString());
});
