I have added a demo of how to overrule heading levels using ARIA:

http://developer-guide.access4all.ch/en/examples/overrule_heading_levels_using_aria

While playing with it, I noticed that NVDA jumps to headings of all levels when pressing the 1 key. The 2 key seems to work as expected.

Is this a bug in NVDA with IE? In FF it works, and JAWS works in both FF and IE.
