Hi Harry,
On the VoiceOver Wiki, there is a page dedicated to just what you are
asking. The link is:
http://blindtechs.net/wiki/index.php/Accessible_Applications
In the case of the Apple Pre-Installed Applications, you will also
find a link to an article on using the specific application with VO.
by no means is this the complete list of all accessible
applications. Hopefully more can be added as I or others learn about
and publish them on the list. If you have any specific questions
about the articles, feel free to contact me off-llist.
Hope this helps.
Later...
