Comment (by rianrietveld):

 Very late to the party, but here's my 2 cents: I agree with helenyhou,
 nacin and lessbloat. Better solve the problem without JS and in a way most
 browsers handle the focus styling, with an outline.
 I love the way Safari solved this: with a nice blue outline for items in
 focus.
 Keyboard users are used to that and then there's no need to burden the
 code with extra JS.

 But I have some questions using the keyboard:
 Using the keyboard I noticed with post.php, there is no focus on change
 permalinks, view post, beta media and upload/insert. Or was there an
 outline missing, couldn't see.
 The span with the permalink has a tabindex="-1". Why? <span id="sample-
 permalink" tabindex="-1">.../?page_id=2</span>

 Further: with a overlay screen like "Choose a Featured Image", the focus
 stays in the page it self and doesn't move to the overlay.
 I found an article about that with a solution:

 success/
 I'm  not sure if this can be used in our case, but it's an issue worth
 looking into.
