Charles,

Thanks for the useful info.

Expanding my question into an area where my knowledge is limited, is it
possible to make pop-up menus that are generated by a mouseover accessible?
An example is the main menu at http://webaim.org (accessibility note: though
the pop-up menus on this page may not be directly accessible, an equivalent
to the menus is provided in the form of a submenu on each page).  Is there a
way to make the pop-up menu directly accessible so that an alternative
(submenu) does not need to be provided?

Thanks,
Crystal Allen
