Using a TiddlyWiki help page

You can also create a simple one page wiki file, using TiddlyWiki, which can then be called from your case.

This approach has the advantage that you can create a dynamic text file, with expanding sections, tags, and cross-linking. The page can be searched.

You can also jump to pre-defined sections within that help page e.g. this section on InfoButtons.

We have now created a simpler, cleaner TiddlyWiki help file (using the newer version 5) which you can embed in your own cases as a self-contained online help. 

For more information about how TiddlyWiki works, check out http://tiddlywiki.com/ where they use their own approach to provide excellent information on how this is used.
