Subject: RE: Question about SC 2.4.3 Focus Order

If forward "navigation sequences affect meaning", going backward would mean the meaning would be lost. I wouldn't expect a page with meaningful forward focus order to preserve the meaning when navigated backwards. 

If going forward and backward do not affect meaning, then 2.4.3 would not apply.

Thanks,

Kathy Eng

Subject: Question about SC 2.4.3 Focus Order

Fellow AG'lers, I am asking that you indulge me in a quick straw poll:  Does SC 2.4.3 Focus Order include backwards navigation?

+1:  yes, of course
0:  not sure / maybe
-1:  no, of course not

FWIW, the associated Understanding Doc has a contradiction between the third paragraph of Intent and the first example provide.  I will be filling an issue (and, hopefully, following up with a pull request) about that, but really I first need a sense of the group consensus before that can happen.

Follows is 2.4.3 and the relevant affiliated definition.

Success Criterion 2.4.3 Focus Order (Level A):  If a Web page can be navigated sequentially and the navigation sequences affect meaning or operation, focusable components receive focus in an order that preserves meaning and operability.

navigated sequentially:  navigated in the order defined for advancing focus (from one element to the next) using a keyboard interface
