body: <pre><code>    if (e.keyCode == 40) {
          // todo click down arrow
          var g = $('ol.list-group &gt; a').hasClass('activeSelect');
          if (g == false) {
              $('a:not(.disable-li)').first().addClass('activeSelect');
          }
          var b = $('a.activeSelect');
          b.removeClass('activeSelect');
          b.next('a:not(disable-li)').first().addClass('activeSelect');
      }
  </code></pre>
