title: Setting focus using left and right arrows (HTML + JS)
body: <p>Is there any to make the left arrow behave like the tab button (set focus to the next focusable item) and the right arrow behave like a shift+tab (set focus to the previous focusable item)?</p>
  
  <p>I've gotten this far:</p>
  
  <pre><code>$().keypress(function(e) {
      if (e.keyCode == 37) {
          alert('I want to do a shift-tab');
      }
      else if (e.keyCode == 39) {
          alert('I want to do a tab');
      }
  });
  </code></pre>
  
  <p>But google isn't being that helpful so I thought I'd put a quick post up here while I google some more.</p>
  
  <p>Thanks!</p>
  
  <p>Oh, and it's purely for FF3.0 so I don't need to worry about other browser nuisances. </p>
