I looked further back in time again, and in Emacs 16.56 (1985!), the isearch.el file already has (in the comments and in the code): "^G means the user tried to quit" "^S means search again, forward, for the same string" "^R is similar but it searches backward" "^W means gobble next word from buffer" "^Y means gobble rest of line from buffer" And ^Q was already bound to isearch-quote-char. At that point of time IIUC isearch was terminated by either ESC or a random control char. Apparently (but I could not find a precise point of time) RET started to mean exit search near the end of the development of Emacs 18, around 1990.
