I know this might be pending how you want to implement keyboard shortcuts through actions on Mac, but it’d be great to have a way to switch between workspaces on Mac with a shortcut. I feel like ⌃1, ⌃2, etc. would be the most conventional, though I’m not deep enough into design to say why.
Edit: I am so dumb, this is really easy to do with the shortcuts system prefs, all your Workspaces are menu items already.
