Title - a javascript snippet to control the document title

This is a piece of Javascript code I use on "Kwissle" to make the document title change temporarily. Other people might find it useful too.

Code looks like this:

var Title = (function() {
 var current_title = document.title
   , timer;

 return {
    showTemporarily: function (msg, msec) {
      msec = typeof(msec) !== 'undefined' ? msec : 3000;
      if (msec < 100) msec *= 1000;
      if (timer) {
        clearTimeout(timer);
      }
      document.title = msg;
      timer = setTimeout(function() {
        document.title = current_title;
      }, msec);
    }
 }
})();
