<p>The &lt;noop&gt; task says that nothing should be done (noop stands for
&quot;no operation&quot;). This tag is used to override deck-level elements.</p>
<p>The &lt;do&gt; tag can be used to activate a task when the user clicks on a
word/phrase on the screen.</p>

      <p>The example below uses a &lt;do&gt; tag to add a &quot;Back&quot; link
      to the card. When the user clicks on the &quot;Back&quot; link, he or she
      should be taken back to the previous card. But the &lt;noop&gt; tag
      prevents this operation; when the user clicks on the &quot;Back&quot; link
      nothing will happen:&nbsp;</p>
