Enum UndoGranularity 

pub enum UndoGranularity {
    InsertSession,
    Word,
}

Controls the granularity of per-insert-session undo steps.

Discipline-agnostic: vim uses InsertSession, VSCode uses Word. Future FSMs (emacs, kakoune, …) may adopt either or add new variants.

Variants

InsertSession

One u step reverts the entire insert session (vim default).

Word

Mid-session undo breaks at word boundaries (non-whitespace after whitespace, or newline). Matches VSCode’s Ctrl+Z granularity.
