License: same as jQuery license.
USAGE:
    // simple usage
    $(document).bind('keydown', 'Ctrl+c', function(){ alert('copy anyone?');});
    // special options such as disableInIput
    $(document).bind('keydown', {combi:'Ctrl+x', disableInInput: true} , function() {});
Note:
    This plugin wraps the following jQuery methods: $.fn.find, $.fn.bind and $.fn.unbind
    not in jQuery 1.4
