I just finished running through some test material put up by Freedom
Scientific.  This is set up to demonstrate their implementation of the user
agent accessibility guidelines, in JAWS 4.5.  I use Window-Eyes, HPR and
Lynx instead of JAWS, but I think this is an  instructive test suite:

http://www.freedomscientific.com/HTML_challenge/html_challenge.html

Lynx and HPR can render the lists properly; Window-Eyes can only do it
while MSAA is turned off.  Similarly, Access keys and the dynamic HTML test
can only be done with W-E while MSAA is turned off.

It's really up to the screen reader developers to decide how much
information to expose while MSAA is in use.  And if you read through the
material from any screen reader/talking browser designer, you will find an
astounding number of hotkeys which a person might want to use, if they
could remember them all.  In JAWS, as was once the case in Window-Eyes, you
have to be careful what mode you're in.  Alphanumeric keys will be used for
typing when the virtual cursor is turned off, then they will invoke a host
of navigation functions while virtual cursor (MSAA) is turned on.  

We live in interesting times!
