<h1>Inline Editing of TreeView Node Labels</h1>
<div class="exampleIntro">
<p>This example demonstrates label editing and keyboard navigation in the <a href="http://developer.yahoo.com/yui/treeview/">YUI TreeView Control</a>. As you interact with the TreeView instance below, you'll find that some nodes allow you to edit them — double-click on node labels to open the inline editor. This example also demonstrates how you can use arrow keys, +/- keys (expand/collapse), and the enter key to navigate and control the TreeView instance.</p>
