FLUID-1821: Image Reorderer instructions for screen reader users

[Anastasia Cheetham]

FLUID-1821 suggests some improvements to the Image Reorderer  
instructions for screen reader users - for example, the instructions  
that they need to turn off virtual cursor.

In trying to implement these improvements, however, some questions  
came to mind that I'm not sure how to deal with.

Here's the source of the conundrum:

We first implemented the keyboard movement using Ctrl + arrow keys. We  
soon found that this key combination was already 'taken' by JAWS for  
another purpose, so we found an unused combination: Ctrl + i, j, k or  
m. Now, the Image Reorderer will work with either of these sets of keys.

The instructions that are both displayed and spoken describe both of  
these keysets. However, JAWS users can't use whichever set they like -  
only the letter version will work for them. Also, it could be argued  
that non-screen reader users don't really need to be told to turn  
virtual cursor off.

So: should the spoken instructions be different than the visual  
instructions? Is this a good idea? A bad idea?

Thoughts from screen reader users? Thoughts from interaction  
designers? Thoughts from people who have thoughts on the issue?
