I'm not convinced making mouse controls more accessible is really all that important. The problem with some GUI applications isn't so much the need to precisely move a cursor and click on tiny icons or in this age where everyone assumes everyone has a smartphone, precisely tap on tiny icons, but that some applications make clicking/tapping the tiny icons the only way of doing things. If every icon in an application has a corresponding keyboard command or menu entry, the need to click tiny icons is eliminated... a universal command to bring up all of a program's pre-defined keyboard commands would probably be handy as well.
And it totally sucks that there's such a wide divide between the discussion area for accessibility, and the discussion area where the people who can address the system level issues are, and I agree it isn't fair if Samuel is the only one acting as liaison between the two... and honestly, this is a discussion that should probably involve both lists... anyone have a link for joining the Debian Boot mailing list? Because I doubt sending a message there will do any good if I'm not on the list to recieve replies sent to the list instead of me directly, assuming it won't just bounce my message for not being a member.
