Amazing video. A lot of the quirks of UNIX and editors like vi make way more sense when you become aware of the role of the teletype in early computing.

  Editors like ed. Vi was waaayyy post teletype.

    Still definitely has some influence though even if it was post teletype

    vi is so-named because it is based on VIsual mode for the standard EDitor. There's less distance than one might think.
    • JdeBP 7y ago
      That includes the distance between the X and D keys? (-: ex, not ed.
      • ink_13 7y ago
        ex is the EXtended standard editor, so it's in the path, sure. But vi and ed actually have many of the same commands.
        • JdeBP 7y ago
          You are still claiming that ed is the one with the visual mode?

  It is a shame that there are no @ or #, otherwise xe could have demonstrated why the old defaults for the line discipline's special characters were as they were. I notice that xe did not attempt to manually turn the iulcl or olcuc line discipline flags on with stty. Linux does not actually support xcase, though, not that there is a backslash anyway. (-:
