asciinema is here since 2011 (although it was called ascii.io until 2 years ago). As for rewinds, you can click on the progress bar to jump to a time you want.

asciinema is here since 2011 (although it was called ascii.io until 2 years ago). As for rewinds, you can click on the progress bar to jump to a time you want. Also, the upcoming version of the player supports fast-forward/rewind/jump keyboard shortcuts: https://github.com/asciinema/asciinema-player/blob/next/src/cljs/asciinema_player/view.cljs#L145-L160 https://github.com/asciinema/asciinema-player/blob/next/src/... As for the playback speed you can set speed, theme, font size etc (embedding docs say this - https://asciinema.org/docs/embedding https://asciinema.org/docs/embedding), and you can append these options to any asciicast URL too, like this: https://asciinema.org/a/21743?speed=5&theme=solarized-dark https://asciinema.org/a/21743?speed=5&theme=solarized-dark Looks like these are not easily discoverable from the player UI, so noting this down. Thanks for bringing this up!
