@pwolfert I took a look at the rendered markdown view of that file and clicked all the links! The external ones are all fixed (🎉 ). Do you know where this confluence document page was moved to?

Keyboard navigation is tested using this keyboard acceptance criteria (Confluence document).

@kim-cmsds, I don't remember what was on the page, but I searched the title and found this document, which could possibly be the successor to it. It does seem to have useful information that fits the context.
