Carriage return or /r has ASCII/Unicode code point 13. m is the 13th letter of the alphabet.
Control codes go from ctrl-a (code point 1), ctrl-b (code point 2) … ctrl-z (code point 26), then Esc (code point 27), 4 more control characters, space, then the rest.

"control codes" go from from `^@` (0) to `^_` (0x1f), with `^?` (0x7f) being an outlier. They're translated from caret notation to ascii value by xor-ing them with 0x40: `#define CTRL(c) ((c) ^ 0x40)`. The space is not a control character. – Aug 04 '19 at 23:28

CTRL+m and CTRL+j are simply "shortcuts" or alternative keys for return

It's not bash's keyboard shortcuts. It's the terminal emulator's effect – 炸鱼薯条德里克 Aug 03 '19 at 21:52
