title: jQuery stopwatch with milliseconds and spacebar as trigger
body: <p>I've just started with 'learning' jQuery, so I almost know nothing. But, I want a stopwatch, showing minutes, seconds and milliseconds. I'd like to start the timer by pressing spacebar, and also stop the timer by again pressing spacebar. Does anyone has an idea on how to do this? Remember, I'm pretty new to jQuery, so a good description would be awesome.</p>
  
  <p>Thanks!</p>
