I think this will work:

    <a id='backlink'
      href='$PageUrl?action=search&amp;q=link=$FullName&amp;fmt=bygroup&amp;list=normal'>$[backlinks]</a>

There are a couple of mechanisms.  One is to create a Backlinks page
containing simply:

    (:pagelist fmt=bygroup list=normal:)

and then you can use that page to display backlinks to any other page.
For example

    http://www.pmwiki.org/wiki/Test/Backlinks?link=Main.WikiSandbox

shows the backlinks to Main.WikiSandbox, while

    http://www.pmwiki.org/wiki/Test/Backlinks?link=PmWiki.BasicEditing

shows the backlinks to PmWiki.BasicEditing.

Still, this comes up frequently enough that I suppose it's worth
having "?action=backlinks" available for any page, so I'll see
about a recipe for that, or possibly adding it to the core if there
are sufficient favorable votes.  (The code to do it is short.)
