Hello,

This is working with Firefox on GNU+Linux but not with other browsers or operating systems.

I'll try and add this ;)

    .bind( 'keydown', function( event ) {
                // cancel on ESC
                if ( event.which === 27 ) {
                    return false;
                }
    })
