Code:
<body id=brighton>
... a little bit later...
<ul>
<li><a href="../birmingham/index.html" class="birmingham" accesskey="1" title="">Birmingham</a></li>
<li><a href="../brighton/index.html" class="brighton" accesskey="2" title="">Brighton</a></li>
<li><a href="../bristol/index.html" class="bristol" accesskey="3" title="">Bristol</a></li>
