-* blind people don't have the opportunity to use a mouse to access content
-* the general means of navigation for blind people is tabbing through content structure
-* video (in particular video that has audio descriptions) needs to have a structure that can be accessed via tabbing through it, to allow (blind) people to directly jump to areas of interest

-POSSIBLE SOLUTION: the structure of the file created through timed text tracks should be accessible from the Web page and access be controlled through a javascript API
