[jQuery] window.home() or location.href='about:home' and Safari 3.1

[Bill]

I'm trying to put together a cross-browser function for
programmatically taking the user to their home page.  So far I have
found this:

  <script language="javascript">
    function gohome(){
      if (typeof window.home == 'function'){
        window.home();
      } else if (document.all) {
        window.location.href = "about:home";
      } else {
        document.write("<p>Please click on your browser's Home
button.</p>");
      }
    }
  </script>

Firefox and Opera like window.home() and IE likes href="about:home".
But Safari 3.1 (for Windows) falls through to the else clause.

Does Safari have a different place in the DOM where the home page can
be triggered using Javascript?  So far I haven't been able to find
anything.

Thanks,
Bill
