I figure I would recall being intrigued by the keyboard's layout, the feeling and function of it, and recall finding it cumbersome at first and then finding it progressively easier. But no, I feel like I've just... always known?
So I'm curious to know how others experience this.
Same as you, I don't remember ever struggling with learning to type or anything. I could just do it.
More recently, I switched over to a Kinesis/Moonlander keyboard, so I had to put in actual effort to relearn to type. It wasn't as easy the second time around...
50 years later, I have bad habits that I cannot break, such as always using the spacebar with my left thumb - annoying when I injured it this year. (Fast typists are shift- and thumb-bidexterous I would assume.)
Then another on Selectrics.
Both with an audio tape audioing "F F F Space."
Good luck.
