That would be a CSS question, not HTML, right? The answer is "no", by
the way, but that's off-topic.

The HTML side of the matter is that accesskeys, as defined in HTML, are
mostly useless or worse than useless, partly because they may interfere
with browser or system accesskey assignments that users are familiar
with and may really need.

So just forget them. And you (your users) don't need tabindex either, if
your form fields are in a logical order, as they whould.
