title: Use up/down arrows to scroll select list but keep focus on input element
body: <p>I want user to be able to scroll through select options with up/down arrows, but be able to press ctrl-c to copy from a matching input element whenever they want, seamlessly.</p>
  
  <p>But I'm having trouble juggling the focus.</p>
  
  <p>The best I've gotten is it works but I have to press down twice to move to the next select element.</p>
  
  <p>Here is a fiddle I created, which isn't even populating the select box for some reason. Though it works on my server. On my server the <code>picsarray</code> array is generated with PHP, but it should be the same effect as here.</p>
