There is conflicting advise regarding the keyboard interactions.
On the Feed Pattern page ( https://www.w3.org/WAI/ARIA/apg/patterns/feed/ ):
It says Control + Home: Move focus to the first focusable element before the feed.
But on the Infinite Scrolling Feed example (https://www.w3.org/WAI/ARIA/apg/patterns/feed/examples/feed/)
It says Control + Home | Move focus to the first focusable element in the feed.
So which is it? When a user uses the Control + Home combination does the the focus go to the first element IN the feed or to the first element BEFORE the feed.
