I think I have even 2 magic recipes :-).

1. Use a terminal like iTerm that supports the Kitty Keyboard Protocol,
and use kkp.el in Emacs. Example from my Emacs C-h k Command-M g ives

  s-m runs the command magit-file-dispatch (found in global-map), which
  is an autoloaded interactive native-comp-function in ‘magit-files.el’.

That requires some fiddling with iTerm key settings so that iTerm itself
doesn't use the Command keys one wants to define.

2. Use something like Devil

In short, that can map input like `. x' to `s-x'. I think there is at
least one other similar package named God, but I haven't tried that.
