title: Selector for grandchildren, or how to anchor the selector on a known element
body: <p>Let's say I have a hierarchy of elements, with <code>#root</code> at its root. I can use <code>$('#root &gt; * &gt; *')</code> to get all its grandchildren. Is there any way I could do that if I already have <code>$('#root')</code>?</p>
  
  <p><code>$('#root').find('* &gt; *')</code> is definitely not it, as it will happily "start" from any descendant for the first star, not just <code>#root</code> children.</p>
  
  <p>Is there any function in jQuery that would "anchor" at the current element, starting with its children or itself? It's been bugging me for a while, and I couldn't find anything similar in the docs.</p>
