I must be in the minority. I haven’t used any of these keys in over a decade. Probably more like 15 years at this point. Command + something can replace almost all of these, so why waste an extra key on it.
You joke, but my caps lock on my laptop keyboard is mapped to command and if I double tap it and hold it’s my hyper key. On my crkbd keyboard if I hold a it’s option and semicolon is control. I have quite a lot of keys like this. It’s very efficient.
