macro editor with timecode? player/recorder

Is there a possibility to record the keys pressed in emacs session & save it in a file (Like macro editor but with timecode). Then run emacs with that recorded sequence from a selected file? In example, make file with timecode & keys. 00:00:01 H 00:00:01,500 e 00:00:02 l 00:00:02,500 l 00:00:03 o In first second it will press letter 'H'. Then half second later letter 'e' and so on. It would be amazing feature to make some tutorials about emacs! I was thinking I could do similar [https://youtu.be/hnMntOQjs7Q](https://youtu.be/hnMntOQjs7Q) Emacs Org Mode Demo 2021 But it would be easier with timecode & keys then record a video.

Check out Howard Abram's package *demo-it*. https://github.com/howardabrams/demo-it Here's a video demonstration of him using it. https://youtu.be/WZVZXp-i7jQ
