KeySequence

Create custom events for sequences of key presses.

How to use

Create a custom event by calling addKeySequence with an event name and an array of key names:

#JS
Element.Events.addKeySequence('konamicode', 'up up down down left right left right b a'.split(' ')); 

Now you can attach handlers to this new event:

#JS
document.addEvent('konamicode', function() { alert('KONAMI'); });
