Hi Ben,

Gez has made some really good points in his last post about the
importance of keyboard accessibility. It really is not an edge case and
shouldn't be considered as such ( I am not saying that you feel this is
the case but I just wish to reiterate it - as its important to be clear).

Yes, but thinking about giving the same logical tab order for all users
is equally beneficial - and I don't see why this cannot be the case.
There is no need to think 'I have got this right for *normal* users (and
BTW if you ever meet any please let me know) and now I must cater for
the *others* or people with disabilities. I am not being facetious here
- it is a fact that good design and development practice can facilitate
ease of use for many diverse needs.

That may be but if a screen reader user tries to do this when using
JAWS, pressing c will trigger an action in their screen reader which
jumps to the first combo box on the page. So be aware that there are key
bindings and combinations that have a pecking order (AT first, browser
second) and it is very easy to interfere with the user experience by
getting this wrong.
