Its a long winded answer Pete. I am trying to make a AA site using a cms joomla (we are almost there ish). I am looking for a component that will allow you to add access keys to the main menus but in the mean time I was going to add some to the template. I can add them to links in the content but the parameters in the dynamic menu system does not allow for this (yet). The only work around I can think of is to add access keys to the template and hide them with css, unless they can be added to the head in some way.
