Scenario: imagine you're watching a movie which comes with an external srt file. That file contains subtitles in English for the movie, but the spoken language of the movie is English and you don't need a transcription. However, there are a couple of times in the movie when a different language than English is spoken (sometimes it could even be a constructed language).
At those specific times I need to activate the subtitles. However, while deactivating subtitles goes well "for free", when I put them on again, the video freezes for a while and it's not as simple as toggling with a key binding.
Any tips to achieve what I want?
