RE: Techniques for WCAG 2.0 H45 longdesc: User agent support ( LC-2792)

Ah, ok, I misunderstood.  We'll have to queue it up for the next release, as I don't think (I'm new at this so I could be wrong, I'll check) that we can easily make that sort of editorial change on its own.  

Thanks,

Hi Andrew,

longdesc in Chromevox has been a reality for some time now. It isn't planed is is real.  Please check previous message. Can that be added now?

What I was asking Dominic about was his direct implementation in Chrome via context menu.

Thanks.

Best Regards,
Laura
