body: <p>In twitter bootstrap, some elements get "greyed out" when the mouse hovers over them. This is true of <a href="http://getbootstrap.com/components/#btn-groups-single" rel="nofollow">buttons</a> and <a href="http://getbootstrap.com/components/#list-group-linked" rel="nofollow">linked list group</a> items.

  <p>Can this effect be triggered programmatically? If so, how?</p>
