To your credit, this does indeed work, but I won't retract my point. It's super-kludgy to go through everything like this, and I definitely can't leave it on all the time. I'm spoiled by the innate tab, shift-tab options of other operating systems. Ironically, when I tried to turn on the accessibility feature just through keyboard nav of Settings, I failed to get to the checkbox (there is at least a global Accessibility shortcut...if it's switched on). I'm at a loss to explain why this particular navigation issue shows up in the Settings app. Other, less critical parts of the OS actually work fine.
