  <pre><code>&lt;select multiple="" id="MySelect"&gt;

    &lt;option&gt;I am Option 2&lt;/option&gt;
    &lt;option&gt;I am Option 3&lt;/option&gt;
    &lt;option&gt;I am Option 4&lt;/option&gt;
    &lt;option&gt;I am Option 5&lt;/option&gt;
    &lt;option&gt;I am Option 6&lt;/option&gt;
    &lt;option&gt;I am Option 7&lt;/option&gt;
    &lt;option&gt;I am Option 8&lt;/option&gt;
    &lt;option&gt;I am Option 9&lt;/option&gt;
  &lt;/select&gt;

  <p>Already tried:</p>
  
  <pre><code>$('#MySelect').bind("mousedown", function (e) {
    // alert(event.keycode)
    e.metaKey = false;
  }).selectable()
  
  $(#MySelect).keydown(function(event){
    if(event.which=="17")
      cntrlIsPressed = true;
    alert(event.which)
  });
  </code></pre>
  
  <p>Didn't work.</p>
