Screen readers and the Lightbox

[Anastasia Cheetham]

I've just finished spending a fair amount of time trying to 'optimize'  
the screen reader experience of the Lightbox. I tested some  
modifications to the markup to try to have the screen readers speak  
something helpful.

I've put together a wiki page of the markup changes that I tested, and  
the resulting experience with various browsers and screen readers:

[ Note that this is similar to Joseph's testing of the title  
attribute, but is testing a number of markup changes. Also, I tested  
using the new keystrokes that don't conflict with screen reader  
reserved keystrokes (some of Joseph's results were the result of the  
screen reader interpreting the keystrokes its own way). ]

I would really appreciate people's thoughts on whether or not the  
described experience sounds reasonable. If you actually have the use  
of a screen reader, you can try it (with virtual cursor or browse mode  
OFF). The working file can be access from the build server:

Follow the "Lightbox with screen reader keystrokes" link

Daphne, I'd also appreciate your input on the modified Instruction  
text. It's more verbose now.
