title: Disable keyboard shortcut in textarea
body: <p>I am using something like this:</p>
  
  <pre><code>jQuery(document).keydown(function(e){
    // code
  }
  </code></pre>
  
  <p>For switching photos in photoalbum with arrow keys.. It works great, but!
  I want to disable in textarea. Because, if I am commenting a photo and I want to move cursor with arrow keys, I switch photo and lose my text :)</p>
  
  <p>How to disable it? Can I catch, which element is focused?
  Thank you</p>
