When I was in high school (in the early sixties) I tried to sign up for typing, which was taught on manual typewriters. I was told that the class was for girls only, and I was turned away. I never did develop good typing skills. I'm pretty much a two-fingered typist. Ironically, I have probably done more typing than 90% of the female classmates who were allowed to take the class.
Precision figured mightily in those days, which may also have pre-dated white-out. Eliminating an error was a big deal. Now it's dead easy, and auto-correct has already fixed several errors in this message.
