NVDA has settings, already there to highlight different focus modes as you go through things.

Yeah, the pages scroll. Although maybe it matters that I have some visual stuff set "on" in JAWS and NVDA: I see highlights with JAWS and I think I have an old add-on to NVDA which does the same (it's good for demoing).

Although it's not uncommon for the virtual focus to go offscreen a bit, but if I keep going the page will scroll. This sometimes happens to me with regular keyboard focus too, but always eventually I get a page scroll.
