I type on a keyboard with only my two middle fingers. This was likely more efficient for my tiny hands at five years old than methods urged by the typing CD-ROMs we had at that time. However as I grew more proportional to a standard keyboard, this early typing style has persisted. I have no idea where to even begin changing this now as it’s been deeply ingrained by decades of habit. Anybody have experience with changing a muscle memory based habit like this?
Chatgpt says 1950s. But who knows if that is accurate
I don’t think so, unless one single brand used them and no one else for the next 40 years.
Electric IBM typewriters from the 90s with keyboards that we would recognise today as a computer keyboard still didn’t have dimples.
I asked a friend with a bigger collection of typewriters to let me know if he notices the bumps on any of them.
