information about frames and accesskey assigned

Hi,

I would like to know if anybody know of web sites that uses frames
and have described the layout and purposes of the frames as it is
recommended in the current page author guidelines? 

The same question can be asked about the use of accesskeys in forms,
I suppose that a consistant use of accesskeys also mean that there
on big sites should be described what keys you can expect to use
in forms? 

Regards
