Re: Is NVDA using the wrong type of widget (tree) to show the headings on a page?

IMO the importance of heading levels depends very much on the type of
content. If headings are being used to chunk up a page, their levels
arguably don't matter very much. But if they're part of a long or
complex document, levels can matter a great deal. Say, for example, if
I were reading through a set of clauses most of whose headings were at
level 2, and I was familiar with one clause and wanted to jump to the
next, whose heading happened to be at level 3, I could easily miss out
on reading a whole clause.

Shall we add this to the "subjective" pile with so much else in the
accessibility arena? :-)

Cheers, Isabel
