I don't like this idea - and the code for it would be a nightmare I think

Yeah - I actually thought about this. What I would like to do is to have
'anchor tags' and so when you refer to something like that you get
'help:panel.sgml?<sect1id>#lockbutton' - I will not start working on this
though until the major mozilla issues are fixed :)
