Earlier quoted context omitted.
That's the same argument Emacs developers use to justify alt (sorry, "meta") + w as copy. But it's a terrible argument. (In the Mac case at least using cmd+c is superior, and even works in Emacs!)
Is that the default meta key? If so then thanks. I've had a really hard time getting that info from emacs users so I haven't been able to try it.
(And macOS's built-in emacs keybindings available in every textbox uses ctrl+opt for meta.)
