You're right!  Indeed, "IMAGEMAP" shows on the status line when you're on
an imagemap link.  It's the same in lynx 2.7.1, which is what I have.
However, I had to switch to "expert" mode.

As to your rhetorical question about whether it's accessible to access
technology.  I suppose it's strictly speaking "accessible" to access
technology, in the sense that in principle you can hear it, but with an
ordinary screen reader you'd have to set it to always speak the status
line, which usually is just the URL which a user would not want to listen
to all the time.  That's a real annoyance I would think.

Hmmm. On the other hand, if you have a screen reader that alerts you when a
particular region of the screen changes, you could set a little 1x1 window
in the lower left hand corner and have it always spoken when it changed.
Then as the user went from link to link nothing would be spoken--because it
would remain "h"--till s/he reached an imagemap, at which point it would
say "I".  Or if it hit mailto: in which case it would say "m".   

The old DOS readers had something like that feature.  I don't know if that
works in a lynx or telnet window in win98.  Experienced DOS screenreader
users will know all this better than I.

Anyway, thats better than having to listen to http blah blah  most of the
time.

So now I get to ask rhetorically: is it "accessible" when the user has to
have that much special knowledge and make such a special setup?
