I hope this is the appropriate forum for my question and if not my apologies.
I'm creating a Drupal 7 site to manage academic course content for various 3rd level modules I must deliver over the next year. I had envisaged a menu structure which would react to keyboard events as well as "on-hover" ones. In other words, when the students click on the course title, a submenu would appear giving course specific information.
Are there better theme/module combinations that I should consider in order to make this as accessible as possible? I have been alerted to the fact that I may have some blind students in the class. Also, as a screenreader user myself, I'd like to produce something that I can easily use. I've been playing around with a few things for example Superfish, however on various platforms and using diverse screenreaders, all the menus I create seem to be permanently expanded. When I set things up so that the top level menu is collapsed, the keyboard does not cause the submenus to appear.
I hope my query is clear and my sincere thanks in advance for any help.
