Speaker notes and transitions are stored in the Slides snapshot and updated through commands, so they stay synchronized with undo and redo.

## Speaker notes

```ts
const presentation = univerAPI.getActivePresentation()
const slide = presentation?.getActiveSlide()

if (slide) {
  slide.setSpeakerNotes('Emphasize the year-over-year change.')
  console.log(slide.getSpeakerNotes())
}
```

Call `setSpeakerNotes(undefined)` to clear the notes. Notes belong to one slide and are not rendered as page elements.

## Slide transitions

```ts
slide?.setTransition({
  type: univerAPI.Enum.SlideTransitionTypeEnum.Push,
  direction: univerAPI.Enum.SlideTransitionDirectionEnum.Right,
  duration: 700,
})
```

`getTransition()` returns the transition resolved for that slide. Direction is preserved only by transition types that support it.

Apply one transition to every slide when the deck should use a consistent effect:

```ts
presentation?.applyTransitionToAll({
  type: univerAPI.Enum.SlideTransitionTypeEnum.Fade,
  duration: 500,
})
```

Call `slide.setTransition(undefined)` to clear a slide-specific transition. Playback consumes the resolved transition described in [Presentation Mode](https://docs.univer.ai/guides/slides/features/core/presentation-mode.md).
