It _should_ be clear to Mac users that "^" == "control" key on a Mac keyboard,
as that's how it is presented for keyboard shortcuts in all Mac menus. But if
it's really irritating then we can also revert that to either "Ctrl" or
"control". It's a quick change.

I just got itched by the "Alt" hint actually, which is not printed on any Mac
keyboard.
