title: Why jQuery's event.which gives different results in Firefox and Chrome?
body: <p>Have a look at <a href="http://api.jquery.com/event.which/#example-0" rel="nofollow">this live demo</a> (from jQuery's site).</p>
  
  <p>Clicking <code>-</code> (dash) in Firefox says that <code>event.which</code> is <code>173</code>, while doing the same in Chrome produces <code>189</code>. </p>
  
  <p><a href="http://api.jquery.com/category/events/event-object" rel="nofollow">This jQuery page</a> says that <code>event.which</code> should be normalized for cross browser consistency. But, it looks like this is not true.</p>
  
  <p>Why is this inconsistency?</p>
