Maybe a typo. I usually just hold down shift for shorter acronyms rather than use CapsLock. But sometimes my muscle memory screws up and I press down the shift separate per letter. Probably a habit from phone keyboard (sticky shift key).
I remapped my CapsLock key to Escape. The only time I ever hit CapsLock was a mistake, so this works out a lot better… and yes, I’m a Vim user so having that Escape close by saves my pinky.
