An n-gram is a contiguous sequence of words within a thought.

• Challenges
  • Must be taken into account by: add, delete, edit, contextView
  • Superscript spacing
    • Dynamically insert spacer sup
    • Re-insert spacer sup whenever it is deleted
    • Do not re-render editable while editing
  • Possible performance issues
  • Leave annotation infrastructure in place
• Convert showContexts from bool to path
• Incorrectly uses selection focus when trying to navigate into thought fragment context view descendants
  • Instead get from contextView
  • Only use selection focus at toggle context view
• Add subkey property to cursor?
  • Might get lost constantly due to { key, rank } reconstructions
  • Can be derived from contextViews
    • No, because selection is lost once you start navigating in
• Can't replace thought with ngram in contextViews as the path becomes ambiguous
  • The same ngam can exist in two siblings
• Append ngram to items for contextView
  • Which makes sense as the ngram is a subsequent navigation step (a selection)
