I actually right now have a keyboard with Æ Ø Å in the place of ;'[ and where a German keyboard would have Ä Ö Ü (don't ask me in which order). The guy selling it put a pad of German keytop stickers in the package but I did not quite see the point in gluing German keytop stickers on a keyboard I was going to use with U.S. layout. I think what makes the bulk of getting used to when switching around and not typing entirely blind is () being shifted 90 on U.S. keyboards and shifted 89 on German (Danish?) keyboards. That's just too close. -- David Kastrup ___ auctex mailing list auctex@gnu.org https://lists.gnu.org/mailman/listinfo/auctex

Yes, I write German texts with that as well. Emacs does offer C-\ runs the command toggle-input-method (found in global-map), which is an interactive compiled Lisp function in ‘mule-cmds.el’. It is bound to C-\,. (toggle-input-method &optional ARG INTERACTIVE) [...] but I find that I don't use this except in emergencies (when the Compose key got lost during some system upgrade and I cannot figure out how to regain it within minutes). My mother is actually an American with a history of writing lots of letters on her U.S. mechanical typewriter, and she is using a German keyboard layout on computers. I don't get that but probably playing around with keyboard layouts is beyond her comprehension. And she does need to write in German occasionally and probably would not get the hang of a Compose key or other contraption not printed on the keyboard. -- David Kastrup ___ auctex mailing list auctex@gnu.org https://lists.gnu.org/mailman/listinfo/auctex

Indeed. I guess Autohotkey is not necessary on Linux: `xkb' lets you remap any key on the keyboard. But, anyway, I'd like to keep most of the keys like they are :) Thanks! -- Denis ___ auctex mailing list auctex@gnu.org https://lists.gnu.org/mailman/listinfo/auctex

Nice indeed. But too bad pressing repeatedly $ while the region is active, it doesn't toggle between ‘$|$‘ and ‘\[|\]‘ (hitting the backslash key on a French keyboard is a nightmare): I'll probably open an issue on this subject on the github repository of `smartparens'. -- Denis ___ auctex mailing list auctex@gnu.org https://lists.gnu.org/mailman/listinfo/auctex

Hi Denis, take a look at the smartparens package (available on Elpa): https://github.com/Fuco1/smartparens/wiki I use it to get self-inserting parentheses and dollar signs instead of Auctex's electric capabilities, and it works fine for the most part.

Ooops, sorry for the noise: I looked at the AUCTeX documentation, but
not at the right place:
┌
│ https://www.gnu.org/software/auctex/manual/auctex/Mathematics.html
└
IMHO, too bad TeX-electric-math is nil by default...
As an extra question, documentation says:
By pressing repeatedly $ while the region is active you can toggle
between an inline equation, a display equation, and no equation. To be
precise, ‘$...$’ is replaced by ‘$$...$$’, whereas ‘\(...\)’ is
replaced by ‘\[...\]’.
But how to get:
- ‘$|$’ with an "unrepeated" `$',
- ‘\[|\]’ with an "repeated" `$'?

Hi Denis,

Yes, of course ;-) You have to customize the `TeX-electric-math'
option
(https://www.gnu.org/software/auctex/manual/auctex.html#index-TeX_002delectric_002dmath):
-- User Option: TeX-electric-math
If the variable is non-nil and you type '$' outside math mode,
AUCTeX will automatically insert the opening and closing symbols
for an inline equation and put the point between them. The opening
symbol will blink when 'blink-matching-paren' is non-nil. If
'TeX-electric-math' is nil, typing '$' simply inserts '$' at point,
this is the default.
Besides 'nil', possible values for this variable are '(cons "$"
"$")' for TeX inline equations '$...$', and '(cons "\\(" "\\)")'
for LaTeX inline equations '\(...\)'.
If the variable is non-nil and point is inside math mode right
between a couple of single dollars, pressing '$' will insert
another pair of dollar signs and leave the point between them.
Thus, if 'TeX-electric-math' is set to '(cons "$" "$")' you can
easily obtain a TeX display equation '$$...$$' by pressing '$'
twice in a row. (Note that you should not use double dollar signs
in LaTeX because this practice can lead to wrong spacing in typeset
documents.)
In addition, when the variable is non-nil and there is an active
region outside math mode, typing '$' will put around the active
region symbols for opening and closing inline equation and keep the
region active, leaving point after the closing symbol. By pressing
repeatedly '$' while the region is active you can toggle between an
inline equation, a display equation, and no equation. To be
precise, '$...$' is replaced by '$$...$$', whereas '\(...\)' is
replaced by '\[...\]'.
If you want to automatically insert '$...$' in plain TeX files, and
'\(...\)' in LaTeX files by pressing '$', add the following to your init
file
(add-hook 'plain-TeX-mode-hook
(lambda () (set (make-variable-buffer-local 'TeX-electric-math)
(cons "$" "$"
(add-hook 'LaTeX-mode-hook
(lambda () (set (make-variable-buffer-local 'TeX-electric-math)
(cons "\\(" "\\)"

I believe this is fixed if you have a recent LaTeX version (2015/01/01
or newer, which is in TeX Live 2016).
> - is synonym to `\begin{equation*}...\end{equation*}' if `amsmath' is

If you set `LaTeX-electric-left-right-brace'
(https://www.gnu.org/software/auctex/manual/auctex.html#index-LaTeX_002delectric_002dleft_002dright_002dbrace)
to non nil, as you as you type "\[", the closing "\]" is inserted
after point.

[AUCTeX] Entering maths
Hi,
does AUCTeX provide something making life easier for inline-math
expressions (`|' standing for the cursor position):
- `\(|\)',
- `$|$' (OK, it's easy to type two dollar signs and go back to write the
expression between the dollar signs, but would be better if done by
a shortcut)?
In the same vein, I know constructing display-math expressions with
`\[...\]':
- has some drawbacks if `amsmath' is not loaded,
- is synonym to `\begin{equation*}...\end{equation*}' if `amsmath' is
loaded,
but does AUCTeX provide something for `\[|\]'?
All the best.
