In macOS 10.13.5 running Emacs 26.1, key presses involving
command+option are not producing the key sequences I expect. How can macOS and/or Emacs be configured to fix this?
I'm using stock Emacs built with
brew install emacs.
It's interesting to note that Mitsuharu Yamamoto's "Mac Port" Emacs produces the expected key sequences. Maybe a patch is required?
