Re: [O] How to represent Emacs keystrokes in Org?
Hi Marcin,
I'm going to reference a hangout of Sacha Chua and Xah Lee
where they talked about this https://www.youtube.com/watch?v=rKPKWqvTImA
( you can download it with livestreamer like so
livestreamer -o xlsc.mp4 https://www.youtube.com/watch?v=rKPKWqvTImA 360p )
At 26:53 Xah Lee starts explaining about how his
setup related to rendering keystrokes in emacs.
At 27:13 he mentions this function => xhm-htmlize-keyboard-shortcut-notation
Apparently this is used to render the keystrokes.

That's what I'd do. Or ~C-x RET f~. You could also use a macro, if you
want it to me be more semantic (I hope I use this word correctly).

I'm thinking at something like this (partially untested):
--8<---cut here---start->8---
#+LATEX_HEADER: \usepackage{menukeys}
#+LATEX_HEADER: \let\ORIkeys\keys
#+LATEX_HEADER: \renewcommand{\keys}[1]{\ORIkeys{\texttt{#1}}}
#+LATEX_HEADER: \newcommand{\repeatedkeys}[1]{\keys{\textcolor{gray}{#1}}}
#+MACRO: kbd \keys{$1}
--8<---cut here---end--->8---
Of course, the macro would have to be improved to work at least (in my
case) in both HTML and LaTeX, by using the @@latex:...@@ construct.

I share your point about a better `org-emphasis-regexp-components' by
default, which would work in 99.9% of the cases.

This might seem a good idea, but how do I do it? (See below for
a concrete problem statement.)

After a while I have to say that my opinion is strongly negative: this
breaks LaTeX export. (LaTeX doesn’t like some unicode characters, it
turns out.) Also, this was really an ugly hack...
So, here is my problem: how to represent a key like M-, or
e.g. a sequence \, (important in regexps) as “code” or “verbatim stuff”
in org-mode? Neither =\,= nor ~\,~ work, of course. Also, I’d like
this to be backend-agnostic, so \texttt{M-,} doesn’t really work.
What is the rationale behind forbidding the comma as the “border”
character in org-emphasis-regexp-components? Should I change this
variable in my setup or is there a more general way to convince Org that
I really want verbatim/code snippets like =\,=?
Best,
