# Type Alias: HistoryGoBackModeType (/pixi-vn/index/type-aliases/HistoryGoBackModeType)



\> **HistoryGoBackModeType** = `"step"` | `"paragraph"`

Defined in: [src/history/HistoryManagerStatic.ts:14](https://github.com/DRincs-Productions/pixi-vn/blob/5bb5bb1f92e38998ea2f477b600168d8da3ece19/src/history/HistoryManagerStatic.ts#L14)

How often a go-back-able checkpoint is recorded:

* `"step"` (default): every single narration step, matching visual-novel-style games
  where the player may want to undo one line/sprite change at a time.
* `"paragraph"`: only when a new paragraph starts (the number of opened labels
  changes), a choice is proposed, or an input is requested - matching book-style
  narrations where undoing mid-paragraph doesn't make sense to the player.
