Hi list,

...any TeX/LaTeX users here?

I recorded this a few days ago,

  ;; (find-1stclassvideo-links "2022tikz")

  ;; Title: Eev and TikZ, or: how to learn TikZ using a REPL
  ;; MP4:
  ;; YT:
  ;; Page:
  ;; Comment: A way to learn TikZ using examples from the manual.
  ;; Date:    2022nov02
  ;; Length:  1:36:27
  ;; Play:  (find-2022tikzvideo "0:00")
  ;; Info:  (find-1stclassvideodef        "2022tikz")
  ;;        (find-eev "eev-videolinks.el" "2022tikz")
  ;;            (find-1stclassvideo-links "2022tikz")
  ;; Index: (find-1stclassvideoindex              "2022tikz")
  ;;        (find-angg         ".emacs.videos"    "2022tikz")
  ;;        (find-angg-es-links)
  ;; You have a local copy of this video.
  ;; The upstream copy of this video has subtitles.
  ;; If you don't have a local copy of its subtitles, run this:
  ;;        (find-psne-1stclassvideo-links "2022tikz")
  ;;    or: (find-psne-eevvideo-links "2022-eev-tikz" ".vtt")

and I'm in the process of finishing its subtitles, and cleaning up its
webpage. All the parts that still need work are on/about the third
part of the video - from 33:41 onwards - that will probably be
interesting only to people who need to learn TikZ.

The first two parts of the video have a lot of material on how to use
eepitch in non-trivial ways. The current version of eev on ELPA -
2022nov08 - has an entry for "2022tikz" in its first-class videos, so
these sexps should work,

  Play:  (find-2022tikzvideo "0:00")
  Info:  (find-1stclassvideo-links "2022tikz")
  Download:  (find-psne-1stclassvideo-links "2022tikz")

and after downloading a local copy people should be able to play it in
mpv in a very high speed and read its subtitles. The keys that I use
for that, and for turning the subtitles and the time on and off, are:

  [ and ]    Decrease/increase current playback speed by 10%.
  { and }    Halve/double current playback speed.
  BACKSPACE  Reset playback speed to normal.

  j and J    Cycle through the available subtitles.
  O          Toggle OSD states between normal and playback time/duration.
