The fine mode caret navigation needs to deal with naigation
between FRAMES and IFRAME elements.  When someone moves the
caret to the content at the end of a frame or the beginning of
a frame does the caret then move to the next frame or not.  If
it does not then the user needs to explicity move focus to the
next frame and start navigation.  This maybe a problem for
many people to understand.  

Currently both Mozilla and IE use TAB to move the keyboard
focus to the next active element and when frames or iframes
are part of the web resource it moves focus automatically
between frames.  I think this is what should be done for fine
(caret) mode navigation.

Here are two test cases from the UAAG test suite that deal
with keyboard navigation of frames and iframes.

These tests mainly deal with simple navigation to links across
frames, but we could make more complex or diverse examples for
testing the mozilla keyboard enhancements.

I think this is one way the user agent working group could
help the SUN Mozilla team is by creating test cases for fine
navigation.
