As extensive as helpful's help-ref? He searches through each and every source file found in the load-path. Where do I look, can you give me some pointer I can start playing with? Or should I do build my own search? > But you probably want this to work in installed Emacs as well? What do you mean by "installed Emacs"? Emacs without sources? Sorry, I just woke up, have to get that coffein going up :). What about to just have a keyboard shortcuts; say 'R', instead of link. With source code displayed it already looks a bit crouded. I think helpfuls buffer looks a bit busy with all the links. I could imagine living with just a shortcut and maybe a context menu item. I attached a screeshots of helpful and built-in help with my yserdays patch both showing source code for the comparison.
