Ahh, WordStar. That was a great editor. Keep in mind, at the time the control key on keyboards was where the caps lock key is now, and there weren’t arrow keys. So the left hand moved the cursor up/down/left/right by characters, words, or screens very easily. Once you used it for a while, it became second nature.
It was easier to write text in WordStar than in vi. That was a hard transition. But WordPerfect was a truly opaque piece of software until you had the ubiquitous templates for the function keys.
We have a code for when we’re ready to leave a party. One of us will go to the other and do the finger walking up the other’s arm. This means “I want to go home.”
