Devarshi, when you say: "A keyboard only user, without an AT, would be benefitted. Users with learning disabilities may learn better. If it accommodates more users, it should be encouraged." Interesting, do you have any studies or data that support your claim? What IF is doesn't accommodate more users? I'm trying to envision how a sighted user (non magnifier, non screen reader, non-AT user) would benefit from tab stops on elements that do not require interaction, like headings and explanatory text in forms? Seems to me they would NOT use the keyboard to direct their eyes to what to read, and would probably be even more confused when the cursor did stop on headings and text when their eyes would already be reading ahead (or behind). I wouldn't think that the blinking cursor is that effective alone in getting their attention without any additional AT doing some voice or highlighting. So, what benefit is there for the keyboard (non-AT users) to stop on headings that are already bold and possible colored/styled differently than the rest of the text? And what about the keyboard user without a learning disability that is trying to be more productive that now has to tab a bunch more times to get to the interactive elements? He or she will hate that web application for doing that to them.

You are correct, there should be other ways—I hope browser vendors could provide a solution. Leon—I agree with you. I have often seen instructional text placed between form fields, which is often difficult to get to, especially when you don’t know where to arrow down from when running a screen reader. Users generally tab when filling out forms, and a tab index of zero, when applied judiciously, does accommodate user groups. I was hoping we can get some direction on a WCAG technique (the intent of this post) that can set the parameters (when, where, how, etc.) for those who are interested. *Phil wrote: Sounds to me like you're trying to play the role of assistive technology when you BOTH make it a heading AND add a tabindex. Requiring the author / developer to add even more mark-up in addition to the heading tag is not the best approach in my opinion. Shouldn't AT developers take on any additional responsibility for the behavior you are suggesting if not already provided? * AT vendors already expose html headings, so I am not sure how they may help in this regard, considering we put a tab index attribute. Yes, project teams / developers should ideally be doing this, and here is why: Adding a tab index attribute (of just *zero*) in certain designs could help users who tab. A keyboard only user, without an AT, would be benefitted. Users with learning disabilities may learn better. If it accommodates more users, it should be encouraged.
