Hello! I'm about to start working on series of slide-show presentations for educational/teaching purposes... While I was investigating the possibility of using (Pandoc) Markdowm to author prsentation, I noticed that e.g. reveal.js (https://github.com/hakimel/reveal.js) has capability to create 'speaker notes': "reveal.js comes with a speaker notes plugin which can be used to present per-slide notes in a separate browser window. The notes window also gives you a preview of the next upcoming slide so it may be helpful even if you haven't written any notes. Press the 's' key on your keyboard to open the notes window. A speaker timer starts as soon as the speaker view is opened. You can reset it to 00:00:00 at any time by simply clicking/tapping on it." However, just a thought that I would have to deal with downloading npm stuff, running local server etc. instead of just having single PDF file is not attractive to me at all. However, I know that one can do it with LaTeX Beamer class - see e.g. https://gist.github.com/andrejbauer/ac361549ac2186be0cdb and there are even applications to help with that like pdfpc: https://github.com/pdfpc/pdfpc and wonder what would be the best way to do it in ConTeXt and/or whether someone has some experience with ConTeXt-generated PDFs and e.g. pdfpc? Sincerely, Gour -- One who sees inaction in action, and action in inaction, is intelligent among men, and he is in the transcendental position, although engaged in all sorts of activities.
