To clarify:

We should split this issue into the following two issues:

[a] Reading (static) text from a canvas element / defining how authors indicate where (static) text is on a canvas element
Define what author guidance and methods should be used to enable users to find and read static text that has been rendered onto a canvas. This might include enabling caret browsing and text selection.

[b] Text editing in canvas
Define what author guidance and methods should be used to create accessible text editors using canvas as a rendering surface.
- or -
Keep existing spec text that advised authors to not implement text editors using canvas as a rendering surface

I've added the recent Change Proposals to the two individual issues.

Thanks for the feedback, Rich.

I think that there are two issues in 131 (text editing in canvas, and reading static text rendered into a canvas element); I have filed change proposals for both.

I think that, for the issue of reading text from a canvas, we should be able to achieve consensus, as you note below.
For text editing, consensus seems less likely.

I propose that we split 131 into separate issues.

Hi Frank,

Thanks for submitting another solution Frank.

I believe this would work provided we add some work under way related to ARIA 1.1.  I am not sure everyone uses the subdom text cursor position.
Another issue is that Macs, currently don't support caret browsing. If you would like me to discuss the work under way I would be happy to do that. In short, I believe this would work but we would need to do the other things.

Note: to the chairs: This is not an alternative to the text baseline. That is another aspect for Issue 131 which would apply to either proposal for caret/selection tracking.

I would like to submit http://www.w3.org/wiki/Reading_text_in_canvas as a change proposal for this issue.

This proposal defines author guidance that outlines a solution to the problem of reading text in canvas elements, improving accessibility.
