     <p>First, the initial selector locates item 3, initializing the stack with the set containing just this item. The call to <code>.nextAll()</code> then pushes the set of items 4 and 5 onto the stack. Finally, the <code>.andSelf()</code> invocation merges these two sets together, creating a jQuery object that points to all three items in document order: <code>{[&lt;li.third-item&gt;,&lt;li&gt;,&lt;li&gt; ]}</code>.</p>

In the first example, the top stack contains the set resulting from <code>.find("p")</code>. In the second example, <code>.andSelf()</code> adds the previous set of elements on the stack — in this case <code>$("div.after-andself")</code> — to the current set, selecting both the div and its enclosed paragraphs.</desc>
