title: jQuery Sortable Move UP/DOWN Button
body: <p>I currently have a jQuery sortable list working perfectly. I am able to move the 'li' elements around. However, how can I make a button to move a specific 'li' element up by one and the one above to move down (and of course the opposite for a down button)? I have looked around google and found very little. Even a link would be fantastic!</p>
  
  <p>Thanks!</p>
