I did in the past but the problem of asccinema for applications like vi or broot is that people don't really understand: you hit two or three keys and the stuff is magically done.

asciinema has a --stdin option to record keypresses - https://discourse.asciinema.org/t/does-asciinema-record-the-...

The bit that's not done yet is rendering an overlay in the web player - https://github.com/asciinema/asciinema-player/issues/79

If seen YouTube videos with an overlay of key presses. Unfortunately I’m not sure how to record something like this.

OBS can do this with a plugin: https://github.com/univrsal/input-overlay
