mozilla-accessibility list has exploded.
We posted a proposed keyboard navigation spec for Mozilla there towards the end of last week, and there have been well over 200 replies so far. Mostly from visually impaired users and assistive technology developers (i.e. people who know what they’re talking about), and with disappointingly-few “me toos” among them, so we’re actually having to read them all 🙂
Tragically the archives don’t seem to be working, so you’ll just have to take my word for it…
