Mac-Ompose

Compose key on macOS. Completely X Window-like.

Note this contains my modifications which you may need to modify. My settings are: CapsLock real key is Left Control and Right Command real key is Compose in the end.

Tested on 10.14.6 (Mojave) and Karabiner-Elements 12.6.0. Feel free to contact me if you have any issues.

Installation

• Install Karabiner-Elements from https://pqrs.org/osx/karabiner/
• Run ./install.sh (it saves one backup copy if overwriting)
• Restart your user session (log out and in again).

Hacking

If you want to hack more, have a look into misc directory.

Gotchas

It generally works, but in applications that eat the <F13> key (like MacVim or iTerm) it does not work. If you have any ready solutions, please let me know. <F13> key needs to be disabled in the Terminal in order to make compose work there.
