Man, why is the good stuff always so hard to find? This
would have saved me from lots of misery. But everything
(always) in time...

I needed to install glibc-doc-reference. I first looked
at glibc-doc:

    Contains man pages for libpthread functions and the
    complete GNU C Library ChangeLog.  The GNU C
    Library Reference manual has been moved into
    glibc-doc-reference for licensing reasons.

That "licensing" bell seems to ring a lot these
days...? (But as long as it is there, I suppose it
doesn't matter.)

Anyway, then set the mode with C-h S. With
autocomplete, I found out that the following choices
are possible:

Custom-mode     apropos-mode    autoconf-mode
awk-mode        bison-mode      c-mode
cfengine-mode   cperl-mode      emacs-lisp-mode
help-mode       inferior-maxima-mode    latex-mode
lisp-interaction-mode   lisp-mode       m4-mode
makefile-automake-mode  makefile-mode   maxima-mode
octave-mode     perl-mode       scheme-mode
sh-mode         texinfo-mode

However, without the manuals for info to access,
probably most or all doesn't come with a lot of
juice. The c-mode is empty, without the
glibc-doc-reference, for example.

So `C-h S c-mode RET'. After that, `C-u C-h S' to
change mode, and `C-h S printf RET' to bring up the
documentation. Well, what do you say? How about: very
good.

PS. I changed the subject of this thread because there
was a person in this group asking for online
documentation for Emacs and LaTeX. I wrote a very
well-composed reply... ;) However, I didn't know about
this and that makes for another ballgame altogether, in
particular because as you see, latex-mode is in the
list below. So now it is just a matter of finding that
manual as well. DS.
