Know which section you're in to highlight a given button:

function getSection () {
   return location.href.replace(/^http:\/\/magic.local\/([^\/]+).*/,  
"$1").toLowerCase();
}

I won't say that it's necessarily the best-written code, but it's not  
daft enough to be shrugged off and it's not particularly contrived.  
It's easy to come up with a bunch of similar cases. If you get one  
implementation with more market-share than the others, then they'll  
have to copy its behaviour, and we'll then have to specify it.
