    https://support.apple.com/en-gb/guide/mac-help/mchlp2262/mac In emacs I certainly use “ctrl-SPACE” a lot in order to mark a location in a a buffer. On macOS that is by default already taken. But you can change it anyway. Read the article above! Where it says “In the list on the left, select a category”, select “Input Sources”! Here we are.
