I don’t know why I always obsessed those «weird» style editor, the feeling just same as Emacs. Even U don’t know what exactly is, what the editor can do. Then u just look in with it and u will say "it’s so cool!".
after try it, the editor really easy to run cpp without Makefile, also have compile error message, and can jump to the error line. But, the editor movement just really not for me :)
