RE: Lotus Notes/Domino accessability QUESTION

Al gilman posted a fine explanation of the twisty problem. Here it is. Thanx 
Al. Also, someone else named John Somebody wanted a description of this for the 
UI issues list. Hope this reaches him ...

[follow-up to discussion of the Lotus Notes/Domino implementation
of expanding lists with inscrutable "+/-" link text on twisties.]

The existing rule about "use meaningful link text" explains why
using plus and minus as the link text for twisties does not work
for screen reader users.  But it does not really tell you what to
do about it because a long substitution would get tedious even in
speech.  We probably need to step back and see what the twisties
are doing for us to understand the problem.

Twisties are used as controls inside what we might call
"accordion lists" by analogy to "accordion file" containers for
information on paper.  These are list structures similar to a
table of contents that the user interface lets you fold and
expand on a section by section basis.  Users of MacOS since
version 7 and Microsoft Windows since Windows 95 will be familiar
with this in the file system interface.

The problem is that the visual user can see where the un-changed
parts of the list come back in the adjusted list presentation.
It is not similarly easy to perceive the structure in terms of
changed and unchanged segments in audio, so far as I know.

Accordion lists are visual context-savers for exploring
hierarchical information structures.  I might even say that
accordion lists are a best current practice for this function.
If there is a comparable best current practice for saving context
inside a hierarchical domain, in the context of an audio user
interface, I don't know what it is.
