Remove page-freeze error, enhance UI input

- Correctly always label the parent node of a newly highlighted element
  as 'known', rather than only sometimes (preventing an infinite
  feedback loop which could freeze pages)
- Implement shift+click keyword for scrolling to previous match
- Try to prevent page from detecting keypresses in keyword inputs
