BEFORE Computers?
George, your word processor WAS a computer, albeit a dedicated one. And the popular control-key combinations are Johnny-Come-Latelies to the computing world. My first experiences with entering text into a computer was with a keypunch machine. One line per Hollerith card; if you make a mistake you throw that card away and start over. You could duplicate the bad card up to your mistake and resume typing from there, but that's the closest you had to "copy and paste" functionality.
These days, I use the "vi" text editor on a daily basis. Vi dates back to the seventies, when computer keyboards did not have cursor keys, so the h, j, k, and l keys are your cursor arrows. After thirty years working in UNIX/Linux, using vi is very natural. The UNIX Korn shell has vi built into it, so you can edit your command-line in the same way you edit text files.
Of course, switching back and forth between modern Windows or Linux applications and vi, I sometimes get tripped up. The control key functions are different in the two worlds, and for some reason modern editors don't think h, j, k and l are cursor keys. Use Ctrl-C in Linux and you'll kill your running program!
