Oh! That's true. I think you have it a bit mixed up though.

- ANSI is the same thing as US, it's the one with a long left Shift and single row Return

- ISO is the one with a short left Shift, two row Return, and the [| \] key in two places

I've certainly used both throghout my life, it seems both are common enough that I never paid it much mind after first learning how to handle a computer during early childhood.

I just checked and out of the 5 keyboards in my home right now, 4 (laptops) are ANSI and 1 (standalone, my daily driver) is ISO.
