title: keydown on checkbox doesn't bubble in FF, but it does in IE. How to solve?
body: <p>Using jQuery, I bind keydown globally like this:</p>
  
  <pre><code>$(document).bind('keydown', function(e) { alert('keydown fired'); });
  </code></pre>
  
  <p>When I press a key having focused a text input field, the alert shows just fine. But when I focus a checkbox and then press a key, it does not fire. Not even with the keypress event. Why do these events not bubble up to the document? They do in Internet Explorer but not in Firefox. How to I fix this? I don't want to bind the keydown explicitly to th checkbox, I want to be able to use delegation. Maybe I can't?</p>
  
  <p>Thx,</p>
