Talk:Carriage return

message: This is linked to a redirect from Control-M??? The return carriage does not have anything to do with the Unix Scheduler Control-M; they are two different things. I don't understand the reference here. —Preceding unsigned comment added by 75.22.20.62 (talk • contribs) 
:I'm not sure what the 'Control-M Unix Scheduler' you're talking about is, but I can tell you why control-m redirects to this page. Under pretty much any command line interface you'd care to name (including bash, Windows' cmd.exe, etc.), holding down control and pressing the m key generates a carriage return, just as if you'd hit the enter/return key. --Dom 04:14, 22 December 2006 (UTC)

thread_title:  Problem With This Article 

message: I think that right now, what this discussion needs is a set of principles that tell us how to determine what a key is. Until we've got that, discussion will keep going round and round. So, here are two questions I'd love to have answered.
What can we use to determine if one enter/return key varies from the other enter/return key?
* We can't use key labelling. Easyas12c points out that, even if we did look at labelling, "how do we know that one of these [enter] keys is in fact return (in disguise)?"
* We can't use key function. Easyas12c points out that "almost every key can be configured to do almost anything. So the key name can't depend on use."
* We can't use the physical codes returned by the hardware. Easyas12c points out that "keycodes vary, so we can't rely on them either." (I'm not sure they do vary, but OK)
If they do turn out different, how would we figure out which is which?
* Again we apparently can't use key labelling, function or elements of the hardware.
I might be wrong, but they look like they're pretty unanswerable under the criteria. The obvious thing to do is to re-evaluate those criteria. In which case, the only important question becomes:
What makes a key, a key: name, function or something else?
In other words, should we be concerned with the nominal issue or the substantive one? I'd love to hear some thoughts. Once we've got that worked out we can easily determine the situation. --Dom 13:35, 23 January 2007 (UTC)

What was the typewriter mechanism called before this? Or was it just not talked about?

replies: text: I took the liberty of switching these two around.  I'm inclined to believe that the original was an old vandalism that went unnoticed, because the teleprinter term coming before typewriters which actually use a physical carriage makes absolutely no sense.  The note there about CLRF makes no sense either, until (correctly, in my opinion) looked at in conjunction with the sentence about teleprinters, NOT typewriters.  But, ah, if someone believes this thinking to be mistaken and can explain how the deuce it makes sense to put it the other way around, please do so. ʎəɹSquaredⓉⒸ 21:09, 31 July 2010 (UTC)
thread_title:  Which Came First 

message: With regards to carriage return denoting end of line, is not CRLF in all systems, but it is common for Windows. It should be noted that old Mac and most Unix (old and new) systems use LF alone, and the newer Macs CR alone. In most devices where space is limited, i.e. handhelds, only one character is used to save space. Windows doesn't convert correctly from just one out of the CRLF combo to CRLF, you need a specialised program.  — Preceding unsigned comment added by 83.216.145.151 (talk) 05:13, 10 September 2012 (UTC)
replies: text: Presumably you meant "new Mac and most UNIX (old and new) systems use LF alone, and the older Macs CR alone", because older Macs only ran the classic Mac OS, with CR as a line ending, and new Macs run macOS, which is a UNIX(R) as of Leopard and thus uses LF alone (all UNIX systems use LF alone).
