On Linux, it feels/looks like cmd+c is still expected for copy to clipboard:

I can right click to see the actions & the keys associated. ctrl+c, as I'd expect on Linux, does nothing. In fact, the ctrl+ keys for cut, copy, paste, select all, as shown in the screenshot do not work. Clicking copy after the right-click does work.

y works as I'd expect in vim in that it only yanks to register and not clipboard. Being able to configure yank to clipboard is more desirable to me than a working ctrl+c, but both are probably good.
