Don't think there will be one, since it may or may not work.

The key is received by X server, then goes to whichever program
that binds this key; if the key is first bound by the window
manager, it may or may not allow rebinds of it.

You'd better play with it in your window manager.

Yagnesh Raghava Yakkala — 2012-05-26T05:19:04

Hello.,

is there a way I can capture alt-f4 (in gnome) and act within Emacs.?

This is because, recent times, I am killing Emacs by mistake with
alt-f4.

I am longing for a function which captures alt-f4 event and ask me for
confirmation in all circumstances.


Thanks.,

Since x equals ("<test< at >adamweb.net>" "Fri, 25 May 2012 23:49:58 +0200"
"Re: plopz" "1648") in your second example, the car of that is
"<test< at >adamweb.net>", and you can't take the car of that again, because
it fails to pass the listp test. I think where you're going wrong is
that nthcdr returns a list, so you can car it. Car itself returns an
atom, so you can't.

Have I got that right?

Also, the whole thing might be easier to read/debug if you use "first"
"second" "third" "fourth" to extract the list elements. Or, if that
seems too unscientific, then "nth", that also pulls a single element out
of a list.

Absolutely not.  Your opinions about keyboards are only shared by
an apparent minority of one: yourself.

Every computer keyboard I've used since the mid-1960s has had the
[Ctrl] key to the left of [A].  I use keyboards 12-16 hours a day
and have NEVER had any RSI or other problems and I've "typed" over
millions of lines of code over a 50 year span (I'm now retired but
I still develop and write a *LOT* of code (programs, scripts, HTML,
etc.)).

My current keyboard can be seen here:

For *BSD, Linux, Solaris and UNIX systems, use xkeycaps to create an

or use the user preferences [depending on the distro or desktop] to
make the [Caps Lock] be another [Ctrl].

Hi everyone ;

I have this function that loops trough a list of lists of email
elements to extract them. The list looks like this :

(("<test< at >adamweb.net>" "Fri, 25 May 2012 23:49:58 +0200" "Re: plopz" "1648")
 ("contact <plop< at >gmail.com>" "Fri, 25 May 2012 22:21:49 +0000" "tst" "1647"))

(This is what you get if you C-h v with point over mail-bug-unseen-mails-one)

(defun mail-bug-desktop-notify-one ()
  (mapcar
   (lambda (x)
     (if (not (member x mail-bug-advertised-mails-one))
 (progn
   (mail-bug-desktop-notification
    "Mew mail!"
    (format "%s %s %s"           ;; Produces the values below

    "500000" mail-bug-new-mail-icon-one)
   (add-to-list 'mail-bug-advertised-mails-one x))))

And this works fine, so it follows that (car (car x)) is the first
element of each atomic list, right ? but when I try to extract it

Re: Umlauts on Mac in 24 pretest

Stefan Vollmar — 2012-05-25T19:05:13

Dear Erich,

if I am not mistaken, one point has not yet been mentioned: you are working on a Mac and there are some arguments for using the same kind of keyboard shortcuts that work consistently for all Mac applications (with a German keyboard, and not only Umlaute). AFAIK, this is not trivial to implement if one wants to have a "peaceful co-existence" with certain Emacs functionality. However, David Reitter has spent a considerable amount of effort to get this just right: it works "out-of-the-box" with Aquamacs. I am currently using one of the nightly development builds (Emacs 94.0.92.3) and can only recommend it.

Warm regards, 
 Stefan

hope Eli answered all your questions.

here's some addition.

• embrace unicode, because it's just going to be more and more.
Programing Languages are all default on unicode by spec (e.g. any html/
css/JavaScript, and Java, Haskell, …). Most OS (Windows, Mac) and file
systems all default to unicode encoding now (not sure about linux).
Even emacs, starting with emacs 23, uses unicode as default internal
encoding.

〈Unicode Popularity on Web by Google〉
http://xahlee.org/comp/unicode_on_web.html

• Unicode is about 2 things: ① a char set with a integer ID for each
char. ② several encoding for the char set, most popular being utf-8
and utf-16 (the latter are default on Mac, Windows). (encoding is a
standard that changes a char from a char set into byte sequence)

• in emacs, just put this in your init:
(set-language-environment "UTF-8")

that should put all encoding to utf-8, and shouldn't cause you any
problem if all your curretn file and elisp file are ascii, because
ascii encoding is compatib

Yes, this part of "C-u C-x ="'s display:

            file code: #xE2 #x80 #x93 (encoded by coding system utf-8-dos)

shows you how it would be encoded in UTF-8.  If you see something like
"not encodable by ...", then you need to set the buffer's encoding
using "C-x RET f".  Under "file code", Emacs shows how the character
would be encoded if the buffer is saved to a disk file or sent to
another program or as an email message.


See above: Emacs shows this under the right circumstances.


On Windows, Emacs always uses UTF-16 to pass text via the clipboard,
because doing so lets Emacs copy and paste any character from any
character set on Earth.


It doesn't.  What it records is the encoding to be used for the
current buffer if it is saved to disk or sent to some program.  That
encoding is a property of the buffer, not of the characters.


Yes, it does.


Yes.  See the section "Text Representations" in the ELisp manual that
comes with Emacs, you will find the details there.

Buchs, Kevin — 2012-05-25T13:40:25

Thanks, Xah and Eli, for contributing to my further understanding. I
went to a specific website where I got the content I copied and pasted
and I can see from the HTML that it has a charset=UTF-8, so I understand
that is Unicode 8-bit. Using the C-u C-x =, I see that the particular
character I pasted has a code point of 0x2013 (U+2013). I didn't see,
however, what the UTF-8 encoding of that code point was. Should I be
able to read that somewhere on the buffer of information I get with C-u
C-x = ? I was poking around the www.unicode.org website, trying to
understand how this U+2013 code point is encoded into UTF-8, but I
haven't determined that yet.

A fresh buffer in emacs for me on my Win-7 box has an encoding system of
iso-latin-1-dos. The coding system used to open and save files is the
same.

So, help me piece together what happens as I paste the UTF-8 text into a
buffer. First, the paste buffer must define that it is in UTF-8. Emacs
reads this information and inserts it into the byte string that defines

This was obvious from the start. You shouldn't have switched to CUA.
