Hmm - ya - I could do that :)
But then again that would be 2 easy! What I ended up doing is databasing
the help system and retaining a 'rank order' in there - so that I can always
quickly calculate the next and previous - dunno why I did not do that in the
first place - but there it is :)
Thanks for the suggest Tom!
