Former "IT" coworker would do that too. He apparently didn't know how to type characters on tge number row, you know like & for example.

I called him out on him using caps lock instead of shift and he asked "what do yoy do, hold shift?" with a tone that implied I was the crazy one.

When I first started to learn touch typing I used some popular documents. It recommended to do that, especially for people with smaller hands. I eventually moved on from it, but I only use left shift since I can’t reach right shift in any sane manner without moving my whole hand.

I do IT stuff in a school and most kids do this.

It’s maddening.
