I have home key on my external keyboard. While home in combination with any modifiers behaves consistently under Linux, it's an utter mess under macOS. Sometimes my cursor jumps to the beginning of the visual line, other times to the nearest \n before the cursor, sometimes when no text editing is involved, it scrolls the frame, other times it does nothing.

First time I tried macOS I was impressed with the globally (so I thought) respected emacs bindings (^E, ^A, and especially ^N and ^P). But then I have painfully discovered that almost every(?) app just mimics the default scheme, but essentially implements its own handling, which leads to numerous inconsistencies spreading way beyond copy/paste. That's when I realized why most macOS users I've observed use touchpad to manipulate cursor during text editing – there's no reliable universally consistent way of doing this under macOS

macOS is not just "not ideal". It's as messy as other OSes, but with its own bag of unique warts.

But I understand it's easy to ignore them once you get used to them.
