Reflecting to my middle school typing class (done on electrical typewriters, not computer systems) I remember questioning why the keyboard wasnt set up in alphabetical order. When my five-year-old asked me the very same question, I was just recently reminded of that. I knew that the answer was connected to the frequency of use of particular letters and likewise the early constraints of typewriter keyboard configurations. But to get a much better answer I turned to YouTube where I understood I had seen a video on the subject not that long earlier..
