The <noop> task says that nothing should be done (noop stands for
"no operation"). This tag is used to prevent an event from occurring.
</p>
<p><b>Note:</b> The <noop> tag can be inside a <do> or an <onevent> tag.</p>

<h2>Example</h2>
<table cellpadding="3" width="100%" class="ex" cellspacing="0" border="1">
<tr>
<td valign="top">
<p>The example below uses a <do> tag to add a "Back"
link to the card. When the user clicks on the "Back" link, he
or she should be taken back to the previous card. But the <noop>
tag prevents this operation; when the user clicks on the
"Back" link nothing will happen: </p>
