Ask HN: Why does nobody use ISO 9995-7 key symbols?

⎋ means Esc (perhaps it looks bad but that's just a font problem), ⇧ means Shift, ⎇ means Alt, ⇱ and ⇲ mean Home and End respectively, ⌦ and ⌫ mean Delete and Backspace respectively etc.

Mac users often record keyboard shortcuts like "⌘ + ⌥ + ⌫" but PC users write Ctrl + Alt + Del whatever... Emacs users have a notation of their own.

No single keyboard cheat sheet (which could save screen/paper space this way), nor even an actual keyboard I've ever seen had ISO 9995-7 key symbols - everybody just uses the names.

Why is this?
