#set( $demo = $text.demo )
$demo.thisPage.insert("#doclink( 'PagerTool' false )"). In this
case, we provide a control to set the item list from a template. Typically,
your "action" class would place the list in the request attributes under the
"new.items" key.
</p>
<p>
If you set a list of items using the "Try it!" form at the top of the table below,
then that will activate a full demonstration of this tool's abilities
<a href="#fullDemo">below the function list</a>. An easy list to begin is a list
of numbers by entering something like <code>[111..2222]</code> in the
"${esc.d}pager.setItems" field.
