      Yes. So is Ctrl+J actually. Ctrl+J corresponds to line feed (LF) and Ctrl+M corresponds to carriage return (CR) ASCII characters. They are typically treated the same way.

        Found it in the classic The UNIX Programming Environment from 1984:

        But then, this is for return, which technically isn’t “enter”, but nowadays they are sort of interpreted the same by programs?

          Yeah, it’s a bit philosophical.

          • In graphical applications, Ctrl+M, Ctrl+J and Return/Enter are all different things.
          • In a terminal in raw mode, Ctrl+M and Return/Enter are the same thing but Ctrl+J is something different. You can for example run bind -x '"\C-j":"echo a"' in bash and Ctrl+J will do something different.
          • In a terminal in canonical mode, they are all the same thing. There probably are some stty options which can change that though.
