Jonathan Chetwynd has raised an issue on the Interest Group - how to get information like text alternatives for images when using keyboard navigation in a browser. Although the solution is to fix the browser, this group specialises in repair tools so seems the place to look for people to help with the work. I have proposed a rough javascript solution, which could be added via a transcoding proxy (for example with XSLT in the case of XHTML content) that changes images from something like <img src="blah" alt="fred" /> <a href="there" title="the way there"><img alt="there" src="imagine" /></a> to something like <a onfocus="window.status='fred'" onblur="window.status=''"><img src="blah" alt="fred" /></a> <!-- I don't know if an a element is enough or if the thing needs to be a link to make anything highlight --> <a href="there" title="the way there" onfocus="window.status='the way there - link to there (http://here/there)'" onblur="window.status=''"><img alt="there" src="imagine" /></a> <!-- I have added link title, "- link to" alt value and href together to get the text. There are probably nicer ways of doing that but I have so far only spent two minutes thinking about this --> Note that this only deals in the window status, so it isn't everyone's ideal solution. In some browsers I believe that the browser can be made to generate tooltips via Javascript, and then such a script could be used to process a page and do nice things. I started to look around Mozilla, but haven't solved it yet (I have a few other things on my to-do list) and I believe that something like this can be done in IE, but I am not sure of that. Anyone know? The thread in the IG that this came from starts at http://lists.w3.org/Archives/Public/w3c-wai-ig/2001JulSep/0232 (it was in the middle of a thread as recorded by the archives).
