Jaws Scripts for Accessibility Links
Сообщение для российских читателей
Здравствуйте российские читатели. Ваша страна платит высокую цену за вторжение Путина в Украину. Путин лжет вам; не верьте кремлевской пропаганде. В России нет свободных СМИ, а интернет подвергается цензуре, потому что Путин не хочет, чтобы вы знали правду. За постыдное поведение Путина заплатят не только украинцы, но и добрые люди России. Пожалуйста, не допустите этого!
Hello Russian readers. Your country is paying a high price for Putin's invasion of Ukraine. Putin is lying to you; do not believe the Kremlin propaganda. There is no free media in Russia and the internet is censored because Putin doesn't want you to know the truth. It is not only the Ukrainians that will pay the price of Putin's shameful behaviour, so will the good people of Russia. Please do not let this happen!
Bruce Lawson recently asked whether adding
rel=accessibility to the HTMl 5 specification was a good idea. Among the initial comments, Jared Smith noted that getting assistive technologies to support the idea might be a problem. For the major screen readers at least, I thought it could be easily solved though.
Bruce's idea went a little something like this:
So I want to float the idea of
rel=accessibilitythat would allow assistive technologies to discover and offer shortcuts to accessibility information, such as a WCAG 2 conformance claim, or a form to request content in alternate formats (for example).
The Immediate reaction to the idea was extremely positive, with only one or two people voicing a concern. From a screen reader user's perspective, the idea certainly has merit.
There are of course many different techniques available to a screen reader user looking for a particular link on a page. It's possible to tab through the links or open a dialogue box listing all the links on a page. It's possible to search the page for a certain key word or phrase. Both approaches will work well, but neither would be as reliable or consistent as the ability to move directly to a link relating to accessibility.
Move to Next/Prior Accessibility Link
The script enables the user to move backwards and forwards between links with the
rel="accessibility" attribute value. Where no such links are present, Jaws reports using the standard short or long message formats, depending on the user's verbosity settings.
Available keyboard commands are notoriously difficult to find in Jaws, particularly where quick navigation keys are concerned. In this case, 8/Shift 8 works well enough for the purpose. The keyboard command can be edited by the user through the quick navigation keys manager, if the chosen one proves unsuitable for any reason.
Appending the script to a quick navigation key made sense for two reasons. Firstly, because it's consistent with similar behaviour for moving through a web page using the virtual cursor. Secondly, because using the virtual.jss file means that the script is only effective when the virtual cursor is in use.
At present, the script has been tested with Jaws 10 on Internet Explorer 8 and Firefox 3.x. When I can find time, I'll run some tests on older versions of Jaws, with older browsers. None of the functions used require Jaws 10 specifically, so the script should be reasonably backwards compatible. Some slight changes may be needed to deal with different browser versions though.
Looking briefly to other popular screen readers, it should be straight forward to script Window Eyes to do something similar. It may also be possible with Hal, but my knowledge of that screen reader isn't up to scratch I'm afraid. SA To Go isn't scriptable, so we would need to wait for the developers to adopt it as a new feature. NDVA could be customised under the terms of the GNU General Public License of course.
