Although you were talking about visually-impaired users and screen

from severe dyslexia often use screen readers for support.


So it maybe unwise to assume that a screen reader user can't see.

What about users with cognitive disibilities? Its a very wide
catagorie which includes, simple dyslexia to extreme mental retardation.
Apparently these people regularly use the web as a  primary imformation
source so must be considered.

Would they understand the wording 'Go to Menu' etc? Never having the need to
use a screen reader its a question I wanted to ask.


A dyslexic using a sreenreader for support almost certainly won't have a 
problem with the wording once they hear it.


At the more extreme end of the cognitive issues group, it's highly 
likely that very basic concepts such as using links will escape them and 
they may have difficulty with all but the simplest of language. In these 
situations, users often need 'hand over hand' support (ie someone 
sitting with them  - explaining and guiding them). Using conceptual 
icons can help both groups to some extent but there does come a a point 
when there is very little a designer can do to alleviate the problems 
and it's really down to training, support and experience at the user's end.

Re: [WSG] Articles/reasearch/experience of screen readers

2006-11-03 Thread Barney Carroll

@Matthew Hodgson:

That's brilliantly useful information, Matthew. It is interesting you 
mention screen magnifying, because it is my company's policy to use ems 
as measurements as far as possible, based on the conjecture that 
partially-sighted people would probably want to increase their default 
font-size, and having the whole site (within reason) scale with that 
would make the whole design far more continuous.


I recently discovered my Mac's zoom function (I'm forever startled by 
serendipity while slipping on F keys) which was nice. On a related note, 
I was horrified to see the effects of what I thought was IE7's text-size 
scrolling (Ctrl + mouse wheel up/down) - IE is still really bad at 
re-sizing images (FF is beautiful) and using this function, rather than 
simply zoom in on the rendered image, it attempts to re-render the whole 
thing based on botched calculations and creates some hideous results. 
This function, however, is not text-size scrolling (as it is with every 
other browser). IE7 still retains the 5 size scrolling but this is 
accessible only through the menu. I think this change is rather bad 
because we all expect those two actions to produce the same process, and 
also it's just not very good and creates a horrible experience for 
anyone who'd wish to use it.


Is default text size adjustment as common as I'd presumed in the 
partially-sighted community, or is it for the majority, as you suggest, 
magnification that is used instead?


@Steve Green:

Steve, what you're doing is exactly what I wanted to hear! Sadly as much 
as I approve and would want to take part, I can't justify this time off 
work - my boss has no problem with sending me to design conferences up 
and down the country, but as far as building on accessibility, company 
policy is just to accept general standards. As long as you can stamp the 
site with 'valid code', 'works without script', and 'no tables'... 
There's no commercial incentive to put any serious work or insight into 
accessibility (at least as far as our practice dictates).


@Frances:

The schism between web designers and developers is a terrible thing 
wherever it appears... And you're right - only pointed work on the part 
of designers to understand developers and influence them is going to 
heal the rifts.

Barney

I'd be interested to hearing from people with actual experience, and or

I also did a very small study on page order with some experienced 
pan-disability users/testers from the Shaw Trust 
(www..shaw-trust.org.uk) about a year ago.


The feedback that I received confirmed the findings above. Users 
expected site navigation to be presented before content. Overall, the 
testers felt that placing content before navigation didn't offer any 
real benefits - especially as it was contrary to their expectations and 
previous experience. So it would seem that, once a 'trend' is well 
established, going against it (even for the best of reasons) can create 
its own issues. Users, generally, don't like being suprised or being 
made to think as they try to move around a site or page.


In a separate, earlier, piece of research, I came across screen reader 
users who preferred to access content before navigation and achieved 
this by simply jumping to the bottom of the page and working upwards 
as standard. So it would seem that screen reader users are perfectly 
capable of developing their own individual strategies to maximise the 
chances of page content being rendered in the order that they prefer. 
But, again, this kind of strategy is based upon the expectation that 
content will be placed after navigation. If you design contrary to that 
expectation, the end result may be disorientations and/or frustration 
for this sub-group.


In the past 12 months, I've not come across any newer studies that would 
suggest anything has changed.


Hope that helps.

on 03/11/2006 11:18 Barney Carroll said the following:
snip
By the way, could anyone elaborate on what tab-indexing is? And how does 
the Alt+# system work? These seem to be crucial elements of screen 
reader browsing but I have a very limited grasp of their convention and 
application.


Tabindexing allow a designer to specify the order in which links or 
controls receive focus on a page when using the TAB key to move around. 
Elements on a page that do not have an associated tabindex will have a 
'natural' ordering (ie follwong the order they appear in the markup). If 
you mix the two, the elements with a specified tabindex will come first 
followed by unindexed elements.


Speaking as an intermittent keyboard navigator/VR user, I consider 
tabindexing to be the spawn of satan - especially when it runs contrary 
to the 'natural' or expected tab order on a page.


For example, if I land on a page which renders some content containing a 
few links followed by a form, I expect to be able to tab to the links 
first followed by the forum controls. One common use of tabindexing that 
I come across in this situation gives preference to the form controls 
and leaves the links unindexed. So, when I hit the TAB key expecting to 
jump to the first link, I actually end up on the form and often have to 
tab through the whole thing to get back to the links which, visually, 
are actually higher up the page. The end result (especially if there is 
a lack of visual highlighting on focus) is often complete 
disorientations and exasperation. On really bad pages, I sometimes have 
to rely on reading the browser status bar just to try and figure out 
where I'm tabbing to!


If I had one thing (OK- one thing amongst many) to ask of other 
designers it would be Please don't create tab orders that are 
unintuitive!. Users (in the West, anyway) expect tab ordering to follow 
a left-to-right top-to-bottom rule and, as soon as you mess with that, 
you create confusion.


By the 'Alt+# system', I assume you mean accesskeys. It's a way of 
defining keyboard shortcuts which, in theory, allow users to jump to, 
for example, the Search item on the menu by selecting ALT+s. Depending 
on the browser being used, the user may then have to press ENTER to 
activate the link. The designer can define which keys, in conjunction 
with ALT (or CTRL on a Mac) relate to which links by means of the 
accesskey attribute.


However, there are problems associated with defining accesskeys on a 
site as they can over-ride pre-existing keyboard shortcuts in the user's 
software.


http://www.wats.ca/show.php?contentid=43

has a fairly comprehensive list whilst

http://www.wats.ca/show.php?contentid=32

also has makes some interesting points.

Since the release of Firefox 2.0, there are also problems with using 
numeric accesskeys on sites.


http://juicystudio.com/article/firefox2-accesskeys.php

My own experience and research suggests that most of the users that 
designers *assume* will want to use accesskeys don't bother with them. 
They vary too much from site to site to be really useful. Providing the 
tab order is intuitive, users prefer to simply tab around pages or use 
options within their own software (which they know far better than a 
random site) to jump to specific points on a page or site rather than 
research a whole list of new keyboard shortcuts on every site they visit.


Gez Lemon and Rich Pedley developed a php AccessKeys class that allows 
users to define their own access keys . In theory, users could define 
the same subset of keys on every site that uses this approach:


http://juicystudio.com/article/user-defined-accesskeys.php

Gez has also since developed an .ASP version:

http://juicystudio.com/article/user-defined-access-keys-aspversion.php

However, I don't think either version has been around long enough, or is 
implemented widely enough, to indicate how many keyboard navigators 
actually use make use of the facility when it's offered. I know I've 
never bothered. :-)

Hi Rahul,

The full article to support the presentation you have linked to is here:
http://www.usability.com.au/resources/source-order.cfm

While no further research has been undertaken by Roger, Lisa or I in this
specific area, we are still working with blind users regularly. In fact, I
have been sitting watching blind users today.

What struck us during testing last year, and has been confirmed on many
occasions since, is that:

1. Source order is often irrelevant as most screen reader users and
refreshable Braille device users [1] have a variety of ways that they can
move around pages quickly (skipping to heading levels, links, forms, form
elements, as well as tabbing quickly through content and doing direct
searches for content on the page). The concept of top and bottom of
pages often becomes irrelevant.

2. Well structured content is a VERY important aid for blind users as it
allows them to use their preferred method of moving around the page. Poorly
structured pages often do not allow this to occur.

3. Assistive markup in forms and tables is also vital. The testing carried
out today confirmed this with blind users having a great deal of trouble
filling in forms due to poorly labelled input elements (or in some cases no
labelling at all).

4. Structural labels are not critical but are quite helpful as they flag
sections of the page. They act almost like street signs, allowing people to
know where they are within the pages content.

One quick test for all of this is simply to turn off all styles and read the
content of your (unstyled) page. Does it make sense to you? Is the content
running together? Are headings helping to break the content into meaningful
chunks?

The second quick test is to then tab around the page with the keyboard only
and see how hard it all is to use.  :)

The experience is different with each type of screen reader due to their quitet propriety ways of operating. Although you can never simulate being blind, running a screen reader with your screen switched off can be an interesting experience.

Have you asked any blind people? There's probably some charitable

You can download trial versions of all the major screen-reading  
applications. (Learning to use them in the same way as a visually

testing.)

Not so. There is plenty of good information out there based on the

Download and use one (or preferably several). And read, mark, learn

only 25
miles from
us (we're
at
Staines,
by
Heathrow)
so you
(and
anyone
else who
is
interested)
are
welcome to
attend our
free
demonstration
of the
JAWS
screen
reader on
Monday 27
November.
It starts
at 1:30pm
and lasts
about 3
hours.

In
conjunction
with one
of our
blind
testers I
will be
demonstrating
how screen
readers
are used,
the issues
facing
their
users and
some
things
that can
be done to
make
websites
easier to
use.

There are
more
details
and a
booking
form at
www.accessibility.co.uk/free_jaws_demo.htm
but you
will need
to be
quick
because
there are
only 4 or
5 places
left.

If anyone
would like
to attend
but cannot
make it
that day
we will be
running
more demos
next year
(this is
the fifth
and last
this
year).
Also
anyone is
welcome to
drop in
for a chat
and a
brief demo
any time.

(have no

all I care

 they

as a

 of

the grail
of smooth

is worth
achieving.
 
 Only I
can never

because I

 I think
the myth

I've just carried out a research project (http://www.roboneill.co.uk/research.htm) in which I observed blind web users in action. You just don't realise the obstacles they face until you see it for yourself. 

Look in your yellow pages for a local self help group, I'm sure they would be happy to let you observe them and their access technologies in action.

Whether
you use
Fangs or a

is
difficult
for a
developer
or tester
to know if
a website
is really
accessible
unless
they have
an
understanding
of how
screen
reader
users
visualise
a website
and
interact
with it.

There is a
huge

between
being able

it. Whilst
it is
possible
to make

every user

It is far
too big a

here, but
problems
include
having too
much

a page,
use of
visual

and the
meaning of
the

being
conveyed
by the
spatial
relationship
between
two or
more
pieces of

In each
case all
the

can be

it may not
be

Complex

That's
because

fortunate
that they

benefit
from some

do such as

Furthermore,
I don't

even if

are?

Screen

Hi all,

Michael - I'm not exactly sure which message in particular you are
replying to, but I have a few comments on this statement you made:

 On 11/2/06, Michael Yeaney wrote:

Perhaps we are doing a pretty darn good job. Sadly though, we are not
in the majority. And therein lies the difficulty. When we talk about
we doing a pretty darn good job, we're talking about - what - maybe 5%
of web professionals worldwide? More, less? I'm not sure but we're not
in the majority as far as I can tell.

Further - you have written about screen reader manufacturers. What,
exactly are the issues that you feel you need to kick them in the
balls about? 

Frances - you said:
I think that poor screen reader software is a very *big* issue that is
generally overlooked since we do not use them.

If we're going to do anything, then we'd better be able to say somethign
more substantial that poor screen reader software - we need to be able
to back it up. (That sounded like I was singling you out, Frances - but
far from it... You just happened to comment)

This is one thing we're attempting to address with the Assistive
Technology Initiative of the Web Standards Project's Accessibility Task
Force [1]. Through this initiative we are talking with screen reader
manufacturers and other Assistive Technology vendors. They are engaging
with us to work together. (Note that we're working with any vendors that
want - for profit, open source, whatever)

(For those of you that don't know, I'm a WaSP member and Lead of the
WaSP Accessibility Task Force)

So if I may make a few suggestions:

1. Let us not kick anyone in the balls. We're part of the same team
here. Lets keep this constructive. Michael - what exactly is it about
screen readers that is bugging you? Frances - what is it about them that
is poor? Anyone else?

2. Are there issues that you want to have us address in our discussions
with them? Or are there things you want clarified?

3. Take these items and email them to me for now - I'm going to figure
out some other mechanism (perhaps on the WaSP site) to collect these
ideas and feedback from you and we'll pull them all together. For now -
email to me is fine (he says with much trepidation!)

Cheers,
Derek.

1. Let us not kick anyone in the balls.
...


Agreed...especially with heavy boots..LoL..onward:

What frustrates me most about screen reader software for the web is
the fact that the only way for them to get information from a document
is to flatten and remove ~2/3's (CSS and script) of the factors that
(possibly) are contributing to the presentation as a whole (be it
audio/visual/etc.)

After working with desktop software for a while before moving to the
web, I can tell you that there really aren't any layout considerations
done on behalf of the software to help accessibility clients (such as
screen readers).  Why???  Two reasons:

1) The isn't any other way to develop the software for the desktop
(you can't change the layout, there are no style sheets to remove,
etc.)

2) From a 'semantic structure' point of view (if there is such a thing
for desktop software), these type s of applications are a mess -
windows nested within windows ad nauseum (OS windows mind you).

3) The are specific API's designed to help convey information to
accessibility clients from the software (Microsoft's Active
Accessibility API comes to mind).

So, in a nutshell, I guess what I'm miffed about is that world of the
web has no matching counterpart, be it in script, tag attributes, or
otherwise, to help accessibility clients discover and convey
information about a site..  Seems like a very big gap, IMO.

Thoughts???

I'd like to respond to this one a little bit later... on to the rest:

1) The isn't any other way to develop the software for the desktop
(you can't change the layout, there are no style sheets to remove,
etc.)

There may not be the ability to change the layout, but there are
layout considerations when developing desktop software. If you are
building a desktop application and drag and drop form fields (a
convenient example, I'll admit) their tab order is in the order in which
they were dragged on to the form or stage or
whatever-the-thing-is-called-in-your-situation. So, what do we do? We
make the layout more linear using the tabIndex property. The linear,
logical order is the equivalent to layout - it mimics to a certain
extent the logical visual layout that is apparent on through visual
grouping, proximity and similarity of style. 

2) From a 'semantic structure' point of view (if there is such a thing
for desktop software), these type s of applications are a mess -
windows nested within windows ad nauseum (OS windows mind you).

I'm not following what you mean here (seriously!) - are you saying that
semantic structure doesn't exist in desktop applications? I'm not sure
how that applies here... Can you clarify?

3) The are specific API's designed to help convey information to
accessibility clients from the software (Microsoft's Active
Accessibility API comes to mind).

Indeed. Windows based screen readers tie directly into the MSA API.
VoiceOver on OSX ties in directly to the OSX Accessibility API, and
other *nix based screen readers are trying to do the same... 

So, in a nutshell, I guess what I'm miffed about is that world of the
web has no matching counterpart, be it in script, tag attributes, or
otherwise, to help accessibility clients discover and convey
information about a site..  Seems like a very big gap, IMO.

I don't think the gap is as big as you think it might, to be honest.

Derek.

Hey Derek - yeah.. I just whipped out a quick response on my way out

I just meant mostly that the software - in my limited experience

Hi Frances - no worries... 

Yes, I would expect it to be difficult for you to use. Guess what?
(Forgive the generalizations about to be written) It is generally
difficult for new screen reader users too. They have motivation on their
side, though. They get used to it. Sometimes it is all they know, and
that is difficult for us to understand because our perceptions of the
web are so very different. I'm not saying that screen readers are
perfect, but they are an incredibly enabling technology that has evolved
over years to find ways to make sense of crappy web sites (you know, the
other 95% of sites that aren't founded on web standards and
accessibility)

I'm hoping to learn more about how users REALLY use them when I attend
Steve's live demo later this month!

A perfect plan of attack, IMO.

I certainly didn't intend to come across as harsh to any party in my

I didn't think you did, but wanted to clarify - if there was something

Re: [WSG] Articles/reasearch/experience of screen readers

2006-11-02 Thread Michael Yeaney

Good points...I'll try to clarify:


There may not be the ability to change the layout, but there are
layout considerations when developing desktop software. If you are
building a desktop application and drag and drop form fields (a
convenient example, I'll admit) their tab order is in the order in which
they were dragged on to the form or stage or
whatever-the-thing-is-called-in-your-situation. So, what do we do? We
make the layout more linear using the tabIndex property. The linear,
logical order is the equivalent to layout - it mimics to a certain
extent the logical visual layout that is apparent on through visual
grouping, proximity and similarity of style.


If tab index was all we were worried about, this discussion would be
over.  It goes way beyond that.  As you indicated, this example was a
bit contrived - even in the web, a document stripped of all supporting
files still maintains tab index.  The same cannot be said for the
implied importance a certain color scheme gives to an element.  If we
could 'notify' the screen readers that some specific DIV was
'important', 'ranked higher' or had 'new content', we have provided a
usable substitute to color alone.


I'm not following what you mean here (seriously!) - are you saying that
semantic structure doesn't exist in desktop applications? I'm not sure
how that applies here... Can you clarify?


I was attempting to draw the parallel with web documents stripped of
all styling methods and desktop apps stripped of layout context (if
that were possible).

If you have ever used Spy++ (an MS tool designed to show handle
references), you would see that even the simplest applications are
made up of many, nested objects that don't necessarily contribute to
the semantic meaning of the application (and in some cases contradict
it).

For example, a simple drop down list (like our SELECT tag) has it's
own window handle in the OS.  Is it a window to the user??? Absolutely
not.  Is it a window in the context of the application???  No. Does
this (on it's own) effectively convey what this control is for?? No.
Not very semantic (by definition, anyway).  Yet desktop screen readers
are fine with this type of hierarchy.

So to bring this example to the web (and to use my own contrived
example), let's say I have an dv / iframe / object floating (visually)
somewhere at the bottom of my web app that is delivering a custom
channel of information that's updated every minute or so, and it
briefly flashes when it updates.  What would be the harm in allowing
me to 'register' this tag with the screen reader as the 'Stock Quote
Feed' to give it some context  And also, when it updates, I want
to the let the reader know via a raised event. I think the WHATWG
was/is considering something like this, but I'm surprised it has taken
this long.


I don't think the gap is as big as you think it might, to be honest.


Maybe not for web content sites that are document-centric to begin
with, but the web application world is not so easy to 'flatten'.  But
that's a topic for another day

HTH,
Mike

I have been following this with great interest.
What I have been considering (I know its been covered before) is putting a 
link at the top of the page,

go to text version
Go to menu

I would think that screen reader users would find that a good addition to be 
able to read an article in text only, and a shortcut to scan articles which 
also have brief title tags in addition to descriptive titles.


In my design content comes first already...

What frustrates me most about screen reader software for the web is
the fact that the only way for them to get information from a document

(possibly) are contributing to the presentation as a whole (be it
audio/visual/etc.)


I'd like to respond to this one a little bit later... on to the rest:


1) The isn't any other way to develop the software for the desktop
(you can't change the layout, there are no style sheets to remove,
etc.)


There may not be the ability to change the layout, but there are
layout considerations when developing desktop software. If you are
building a desktop application and drag and drop form fields (a
convenient example, I'll admit) their tab order is in the order in which
they were dragged on to the form or stage or
whatever-the-thing-is-called-in-your-situation. So, what do we do? We
make the layout more linear using the tabIndex property. The linear,
logical order is the equivalent to layout - it mimics to a certain
extent the logical visual layout that is apparent on through visual
grouping, proximity and similarity of style.


2) From a 'semantic structure' point of view (if there is such a thing
for desktop software), these type s of applications are a mess -
windows nested within windows ad nauseum (OS windows mind you).


I'm not following what you mean here (seriously!) - are you saying that
semantic structure doesn't exist in desktop applications? I'm not sure
how that applies here... Can you clarify?


3) The are specific API's designed to help convey information to
accessibility clients from the software (Microsoft's Active
Accessibility API comes to mind).


Indeed. Windows based screen readers tie directly into the MSA API.
VoiceOver on OSX ties in directly to the OSX Accessibility API, and
other *nix based screen readers are trying to do the same...


So, in a nutshell, I guess what I'm miffed about is that world of the
web has no matching counterpart, be it in script, tag attributes, or
otherwise, to help accessibility clients discover and convey
information about a site..  Seems like a very big gap, IMO.


I don't think the gap is as big as you think it might, to be honest.

Cheers,
Derek.

RE: [WSG] Articles/reasearch/experience of screen readers

2006-11-02 Thread Steve Green
A 'go to text version' link certainly won't hurt, but our experience of user
testing is that they are rarely used. In fact we did a test project last
week where the site had a text version, an audio version and a built-in
magnifier, but only one of the three users (who was a screen reader user)
even noticed any of them. However, despite having some difficulties with the
site he never tried the text-only version.

Maybe this is because in the past text-only versions were maintained (or
not) separately and often had outdated or incomplete content. Obviously it
is possible to generate both versions from the same content but few sites do
this.

We also came across a site that had no fewer that six 'skip to' links such
as 'skip to main navigation', 'skip to sub navigation', 'skip to main
content' etc. The whole thing was so verbose that they really needed a 'skip
past all these skip links' link. The point being that screen reader users
benefit from pages being as terse as possible (i.e. less to remember), and
that sometimes they are hindered by features that have been added to help
them.

With regard to 'title' attributes, by default these are not read by most
screen readers. Some have an option that allows the user to read them but
that's little use because the user has no way of knowing if an element has a
'title' attribute except by trial and error, and it's too much hard work to
keep checking.

My email program mangled my previous emails today, so in case anyone missed
it, we're running a free JAWS demo on 27 November. Full details and booking

RE: [WSG] Articles/reasearch/experience of screen readers

2006-11-02 Thread Matthew Hodgson








When I worked at the National Library we
had Vision Australia
(used to be the Blind Society) look at the new Libraries Australia website.



You can pay for them to go through a site
and theyll tell you and show you whether it can be used by visually
impaired people. It is a real eye opener to see what they do and how they use a
site. 



In the end, we learned the following
lessons about vision impaired users and screen readers:



a) Only a completely blind person used the screen reader. Most people
with a visual impairment will use a screen magnifier  that brings a
completely different perspective to things. They only see a small piece of the
website at a time. Itd be like looking at a screen only through a
magnifying glass.



b) Consistency of layout is important. If you have a 3 column layout,
use it throughout the site. They will get an expectation of component x to be
in the same place for every page. If it is not they will have a hard time
trying to find it.



c) Keep it standards compliant and make sure the (x)html code
validates (if you get this right then its easier to get the accessibility
right)



d) Make sure that the flow of narrative through the document makes
sense if you take the css away. Use headings to differentiate between menus and
content



e) Make sure that when images are content they are in the document.
Otherwise, use css to make them part of the design.



f)
Adding tab
order through your menus is helpful.



g) Forms are trickiest. We found it best to make sure that the words
came first and then the action. Many people are tempted, for example, to put
the checkbox first and then the words next. 



[ ] Male
[ ] Female



They
wanted to see it this way:



Male [ ]

Female [
]



This
also had more sense for the blind person with the screen reader. It read the
text before saying there was a checkbox. Same thing for search. Use the word
search, then the text field, then the button. 



Then
there was the things about using labels for forms, table/column headers and
captions. All these things make it easier for the screen reader, but not for
screen magnifiers.



Hope
this is of some help

Re: [WSG] Articles/reasearch/experience of screen readers

2006-11-02 Thread Jan Brasna
I would love any links to articles/archived polemic/research studies/the 
appropriate list... If anybody here has actual experience of a screen 
reader, I would be overjoyed to hear from them.


Joe Clark or James Edwards aka Brothercake are practicing screen reader 
testing with various some-technology-enabled sites to test AT 
behaviour.[1][2] (Plus there's one more on this from Bruce Lawson.[3])


If you're looking for a dedicated forum, you could try 
AccessifyForum.com [4] ...


BTW I use VoiceOver on MacOS X pretty often. The same goes for inverted 
color scheme or zoomed screen - my eyes simply hurt after a whole day 
stuck to a display...


The issue I see nowadays is where the assistive technology doesn't quite 
catch up with the recent best-practice (sorry to lean it all towards 
JS/DOM...). One thing is having an accessible content, however I really 
believe the AT should be built in the system in such way that it could 
really handle all the information a sighted user could get, and process 
it for the screen reader. Derek, I'm talking about non-linear DOM 
changes or generally event announcement. I think we quite agreed on that 
with Tomas Caspers and Brothercake.


BTW a half year ago I commented on this topic under Garrett's 
article[5], and maybe made the same mistake of mentioning turning JS off 
as Derek did some time ago if I'm not mistaken.

Hello,

putting a
link at the top of the page,

Bruce,  What about users with cognitive disibilities? Its a very wide
catagorie which includes, simple dyslexia to extreme mental retardation.
Apparently these people regularly use the web as a  primary imformation
source so must be considered.

Would they understand the wording 'Go to Menu' etc? Never having the need to
use a screen reader its a question I wanted to ask.
Kate
