I learned how to type in the 60s with a record and workbook that came with my dad’s portable typewriter. It was fun. I had no idea how many man years I was to end up spending on a keyboard.
I have been able to touch type numbers though. I have to stop and look if I type a number.
Here's something I can do ~ if you ever took the mavis beacon typing tutorial, or used it to teach others, it has a random letter generator ~ spits out nonsense words. I can type them as fast as copying anything else, or typing on FR. One of the reasons was that practice typing numbers because that random generator throws numbers into the mix.
My kids were encouraged to type by them watching me BEAT THE MACHINES. They do great. Both can barely print or write.
