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!
