Thanks again, Mat! You. Are. Awesome. After reviewing your set of triggers, I was able to create a multi-caption project with buttons to play/pause the video and toggle the captions on/off. I used public domain audio and video, and you can see it here:

Our projects include video with narration, and I associate the English version of the .srt file for the first set of captions. But we'd like to give viewers the ability to switch to closed captions in another language. Sadly, when I add copies of the audio track with different .srt files (French, Spanish, etc.), I can't find a way to pause/seek/scrub the audio and related captions file when the viewer moves the seekbar on the slide.
Any suggestions are welcome! In the meantime, I'll submit a feature request :-)
Thanks again for all your help - take care!
