| May 3, 2022 at 3:05 | comment | added | user3528438 | I wonder when and which machine first changed "return" to "enter". Some non-English-speaking countries never made the change, e.g. in Chinese they still call it "Hui-Che" (return carriage). | |
| Apr 19, 2022 at 21:25 | comment | added | cup | I think the sequence was LF, CR, DC1 or DC3. The DC1/DC3 was just a dummy character to prevent the teletype from typing the first character of the next line in the centre of the page. | |

another reversion to ASCII characters, for those systems that do not support newer characters

| Apr 13, 2022 at 8:41 | comment | added | paxdiablo | I wonder whether linefeed first may have been advantageous to get the just-laid-down ink out of the way in case the carriage return may have smudged it. | |
| Apr 13, 2022 at 8:37 | comment | added | paxdiablo | @HotLicks, I always made a point of sliding the carriage by using the wheel section then using the advancer lever to scroll the sheet. But, then again, I always was a bit of a rebel :-) | |

revert the pure-ASCII drawings, as not all browsers can support it

| Jul 15, 2020 at 14:27 | comment | added | DrSheldon | @ThorbjørnRavnAndersen: Do not make assumptions about me. I did have such a manual typewriter, and it was just as likely to make either of the two possible movements. | |
| Jul 15, 2020 at 13:00 | comment | added | Thorbjørn Ravn Andersen | Get an old fully-manual typewriter and use it a bit. The icon will make sense then. | |
| Jul 15, 2020 at 11:00 | comment | added | Walter Mitty | Key to the history of CR+LF is the timeframe 1963-1968. At this time, computers began using the ASR 33 Teleprinter as a console interface. I'm thinking of the DEC PDP-4 through PDP-10, but there are plenty of others. You can review the history here. | |
| Mar 22, 2020 at 0:33 | comment | added | jez | While I can't tell you the history of why the decision was made, regardless of what order the CR and LF are sent or physically carried out I have always thought that the visual metaphor makes sense the way it is: enter/execute the command (downward flowchart direction) and then go back to the beginning of the line to wait for a new command. If the arrow went back to the beginning of the line before going down, then every time I press it some part of my subconscious would think that I'm deleting the command I just typed. | |
| Mar 21, 2020 at 22:59 | comment | added | Hot Licks | There used to be this thing known as a "typewriter". The carriage return lever on it would first scroll up the paper, then slide the carriage to the right, so that the left side of the paper was ready to receive more printing. | |

| Mar 20, 2020 at 21:57 | comment | added | JdeBP | I'm surprised, given the Retrocomputing readership, that no-one pulled you up on your pressing Enter rather than pressing Return. (-: | |

I have used cr/lf all my life, and never once had to think about it being backwards until today! Now, I will be incapable of not thinking about it every time I press "enter"... like now! | |
