GOTHEEK  Like so many other help "tools" this one makes assumptions about the state of the application -- expecting specific things to be available (such as shortcuts) -- and then won't work unless you have the mac developer tools installed. Most applications do a check if something that's a requirement is installed. And if not, it'll stop before you waste time creating a help file.

I'll be sticking to HTML.
