@mltony please don‘t disable vertical nav, this one works properly in Kindle and is very useful. Or do you get certain errors when using vertical nav?Thanks.

But vertical nav relies on the same function _moveToNextParagraph that according to my testing gets stuck in Kindle. Try using vertical nav in the same test case where your text nav keystroke caused NVDA to hang - I think vertical Nav would hang as well.
