We have just added two important pieces of information to get things working.
One is the keys currectly used by the browser (hotkeys) and the other one is the DTD needed to create valid browser3d documents.

You can use the examples in the default homepage and the links from it of browser3d in this url:

http://browser3d.org/3d/index.php (You can load it in your 2d browser firefox, iceweasel, mozilla, safari, konqueror, ie ... to view the source)

Hope this will be useful
