...or in properly constructed editing environments.  It's a UI tool
problem, not a user problem or implementation problem.  

In fact, should we want to take this further, it could be argued that
'accesskeys' are hidden meta-data too, thus should be considered a
hindrance or barrier and removed from the spec. (and to be clear, I am not
currently advocating that - in fact I've been turned around on
accesskeys). Tab, don't let your eyes and vision be your disability, start
thinking outside of the box a little.

Thank you Shelley for a more metered response than the one that was
brewing in my head.

What she said!
