Hello,

When pressing the TAB key, the indentation doesn't happen. Even, the
text is translated as in a Word or LibreOffice document.

By the way, \mathbb{R}^{*[*0,\infty)} breaks the indentation too on emacs
25. It's the probabilists notation... With \mathopen and \mathclose, it's
fixed :
\mathbb{R}^{\mathopen{[}0,\infty\mathclose{)}}

How do pass to emacs26, apt-get install emacs26 answers 'not found' ?

This breaks the indentation too :

\newcommand{\intervalleof}[2]{
  {\left.\vphantom{#1#2}\right]}
           {#1}
           \mathpunct{};\mathpunct{}
                     {#2}

If the problem is that you were using the wrong major mode, could you
please elaborate on what the bug is?

Which distro are you on?  Emacs 26 was introduced in Debian 10 (codename
Buster) and Ubuntu 19.04 (codename Disco Dingo).

Sorry, I don't understand what you mean, can you please elaborate?
Which mark-up mode are you referring to?  How does it relate to *.c
files?

By default, Emacs opens *.tex files in tex-mode (see auto-mode-alist).
This is a generic parent mode which tries to guess which specialised
submode to enable (see tex-guess-mode).  Evaluating the following, for
example, should place you in a latex-mode buffer:

  (find-file (make-temp-file "my-" nil ".tex"))

If tex-guess-mode guesses incorrectly, there are several other ways to
specify the desired major mode, e.g. via an auto-mode-alist entry,
file/directory variable, hook, or otherwise (including the obvious
M-x latex-mode RET).

as the file had the '.tex' extension, I expected Emacs would indent it by
pressing the Tab key

So if I read this discussion correctly, the problem is, quoting SE:

    The problem is likely that your other files use tex-plain-mode
    instead of latex-mode. The .tex extension is used for both, so
    Emacs tries to guess, and it tends to err on the side of
    tex-plain-mode.

    You can add a -*- mode: latex -*- somewhere on the first line of
    your files to avoid the problem.

Is this something we would like to change, or is this working as
expected and therefore notabug?

Best regards,
Stefan Kangas

bug.

Please reply back if this is an issue and we can reopen the bug.

Best regards,
Stefan Kangas
