I've no idea if this is useful, but the latest RDoc now has a JavaScript thingy that pops up the source of a method when you click on a button. There's a sample online at http://rdoc.sourceforge.net/doc/index.html and a download is available at http://sourceforge.net/project/showfiles.php?group_id=42128 (The home is rdoc.sourceforge.net) There are still some known issues, but I'd appreciate bug reports, comments, and so on. Thanks Dave
