Many video playback devices or apps have some way on their remote to do a skip backwards of N seconds, with N typically somewhere from 10 to 30 seconds.

What I would really love would be a way to do that and at the same time turn on subtitles (or captions if subtitles aren't available in your language) for N+10 seconds. A separate button for this would be ideal, but a setting that makes the regular skip backward also do the subtitle thing would be fine too.

Alternatively, I'd be OK instead with a "toggle subtitles" button that toggles between subtitles off and subtitles on (with the language being whatever one was last used).
