From [0]:

[For Bash] Ctrl + x + Ctrl + e : launch editor defined by $EDITOR to input your command. Useful for multi-line commands.

I have tested this on windows with a MINGW64 bash, it works similarly to how `git commit` works; by creating a new temporary file and detecting* when you close the editor.

* Actually I have no idea how this works; does bash wait for the child process to stop? does it do some posix filesystem magic to detect when the file is "free"? I can't really see other ways

It does create and give a temporary file path to the editor, but then simply waits for the process to exit with a healthy status.

Once that happens, it reads from the temporary file that it created.
