MS PowerPoint's Rehearse Timings feature, found under the Slide Show tab, lets a presenter record exactly how much time is spent on each slide while practising the presentation.

How it works:

1. When activated, the presentation starts in full-screen mode along with a small recording toolbar showing an elapsed timer.
2. The presenter proceeds through the slides — including any animations and narration — at a natural pace, just as they would in front of an audience.
3. PowerPoint records the duration spent on each slide, keeping it synchronised with any narration and animations associated with that slide.
4. At the end, the user is prompted to save these timings; once saved, the option to use the recorded timings is automatically enabled in the slide show settings.
5. During the actual or exported presentation, the slides then advance automatically after their recorded duration, without any manual clicking, keeping the pacing consistent with the recorded narration and animations.

This is exactly what the question requires — automatic slide advancement synchronised with narration and animation timings.

The other tools serve different purposes: the slide sorter view is simply a thumbnail arrangement used to reorder, add, or delete slides — it plays no role in timing or narration. Action buttons are clickable shapes inserted onto slides to let a user manually jump to another slide, another file, or a website — useful for interactive, self-navigated presentations rather than automatically timed ones. Presenter view is a dual-screen feature that shows the presenter their speaker notes, a preview of the next slide, and an elapsed clock on their own screen while the audience sees only the current slide — it aids delivery but does not record or apply automatic slide timings.
