Enabling Control-Meta(⌘)-D on macOS
I use command (⌘) as my Emacs Meta key. Recently discovered C-M-d is not available to Emacs for binding keys on macOS. Stack Exchange had the workaround:
defaults write com.apple.symbolichotkeys AppleSymbolicHotKeys -dict-add 70 '<dict><key>enabled</key><false/></dict>'
