Re: Why use CTL-x CTL-c to quit instead of CTL-x CTL-q?

Jean already provided a precise reply to your question. I've seen
several questions about the Emacs interface over the past year or so.
Indulge an old crank for a couple minutes. I will offer a more general
reply on why I think the Emacs keybindings are the way they are.

Emacs availability predates Windows and Unix by a fair bit. It
predates common graphical user interface technology by more than that.
In fact, Emacs was popular enough by the time Windows and Unix were
around that other implementations of Emacs existed before that, both
as spin-offs of the GNU Emacs codebase as well as complete rewrites.
The Wikipedia page about Emacs provides useful background:

https://en.wikipedia.org/wiki/Emacs

GNU Emacs first appeared in 1976 or thereabouts (and not on Unix).
Technically, Unix had already moved through several versions by that
point, but it was still captive to Bell Labs.

In contrast, Microsoft Windows didn't appear for another ten years or
so as a response to the success of the commercialization of graphical
user interfaces by Apple's Macintosh.

ISTR Stallman was resistant to a port of Emacs to the Mac before the
release of Mac OS X, largely because of his stance on closed-source
software. I believe he was resistant to a Windows port for a long time
too. It was a different story after the release of Mac OS X, since it
was a Unix-based system under the covers. I don't think Stallman could
have resisted the port at that point.

By the time that Emacs was available on Windows and Macs, we are
talking well beyond the mid-80s. I don't know when a Windows port
became available, but Mac OS X wasn't released to the public until
2001. I'm not sure when it was ported to Windows, but likely not
before version 19.24. See the release history table here:

https://en.wikipedia.org/wiki/GNU_Emacs#Release_history

So, Emacs's roots lie in the pre-Unix/Windows/Mac history of
computing. Nearly as important, they lie in the pre-GUI history of
computing. By the time Windows, Unix and Macs were around, the Emacs
user interface was quite stable. While users can (and do) do pretty
much anything they want w.r.t. key bindings, I don't think changing
the defaults as the winds of computing changed would have been the
right thing to do. There is value in a certain amount of consistency,
even if it isn't "perfect."

P.S. Do vi/vim users wonder why its key bindings don't correspond more
strongly to common Windows, Mac or Unix/Linux interface standards? I
rarely need to use vim, but if they changed the quit command (:q or
:q!) I'd be completely lost. How would I ever get back to the shell
prompt? Oh, right, C-z followed by kill(1).
