Hi guys

Good observations.
Yes, I had to step in and comment on a site that had literally 25 or
30 "AccessKey" shortcuts, that absolutely no one was using (I am also
a part of the screen reader training team, and my colleague, who has
done this for 10 years, said users did not want this).
It took some time to convince the site admins about this, but I have
managed to get them to remove all but two AccessKey attributes from
the site.
As I said, I still believe the AccessKey attribute is useful, if used
very sparingly and in situations where a link is used very often, but
is not immediately accessible in another way (think the alt-i for
Inbox on www.gmail.com .. using Basic HTML).
I agree with everyone, I just think the "few keystrokes" philosophy
might work as a sort of teaching technique/challenge for web
accessibility presentations more than anything.
I am mostly thinking of how we can get regular web developers, who
perhaps attend a lecture on web accessibility in school or
professional education series, actually intreagued or interested
enough to really give these problems some thought, and something
concrete like this seems to be a good point to create discussions
around. At the same time, as you guys point out, we don't want to
simplify the problem of accessibility to a check list or a number,
because it is, fortunately or unfortunately, more complex than that.
