I just upgraded to Fedora 7, which means I got upgraded from
emacs-21 to emacs-22. Now I find that when I edit a TeX file,
all subscripts (TeX _{xxx}) and superscripts (TeX ^{xxx})
are rendered in small type, lowered or raised on the line.

Since TeX is a markup language not a WYSIWYG application
this is not helpful to the readability of the TeX source.

How do I switch off this new behavior, while keeping the syntactic
color highlighting (font lock) that is helpful when composing TeX?

Are you using AUCTeX? You can see this in mode-line, menus, and  
*Messages* buffer. Then switch its use off! For example by finding  
the Elisp file that loads or requires tex-site ...

You are more likely wanting to use AUCTeX so you just have to customize:

Font LaTeX Script Display
Font LaTeX Superscript Face
and
Font LaTeX Subscript Face

The Emacs-builtin TeX mode has this feature as well (it even had it
before AUCTeX, IIRC).

Nonsense.  In AUCTeX, there's a variable to turn it off and customize
it.  There's no option to turn it off in the Emacs-builtin TeX mode,
CMIIW.

You should be able to customize the two faces `subscript' and
`superscript' defined by tex-mode.

Did that do what you want?

Thank you all for your help.

Can you tell me how do I do that by putting commands in my .emacs file?
I would like a general solution that I can port to many computers, not
a point-and-click routine that I have to re-do on each machine.

No, I am just using the regular emacs that came packaged with Fedora 7.
I don't see the word "AUCTeX" anywhere. I don't think it is even 
installed on my computer.

I don't want to use AUCTeX, I just want to revert the way emacs-22
tex-mode treats super/sub scripts back to how it was in emacs-21.

How about reading the doc strings or play around with customize?

Set `font-latex-fontify-script' to nil.  That's all.  Or, if you only
want a smaller font, but no raise or lower, set
`font-latex-script-display' to nil:

,----[ M-x customize-variable RET font-latex-script-display RET ]
| font-latex-script-display: [Hide Value]
| Choice: [Value Menu] No lowering

Yes, I just could see that 'emacs -Q' shows this behaviour, too. I  
think you will need to edit tex-mode.el not to raise (positively or  
negatively) anything ...

I can, but I'd like to hear first that doing this interactively solves
your problem.

I can control their size but not their raising/lowering.

Edit -> Text Properties -> Display Faces
   click on "superscript", up comes window of properties
   uncheck "height"
   click on "save for future sessions"

This makes superscripts come out the right size, and adds
to my .emacs file the following:

(custom-set-faces
  '(superscript ((t nil))))

All I need now is a way to get rid of the raising of superscripts.
If that isn't a Face property, what is it?

I was afraid of that.

It seems to be explicit code, see tex-font-lock-suscript.  Perhaps you
will be able to fix that by tweaking tex-font-lock-keywords-3, but
that means editing tex-mode.el.

I suggest to submit a bug report asking for this feature to be
customizable.

Since AUCTeX adopted this functionality from Emacs' default modes
rather than the other way round, I doubt that your advice is of any
use in his situation, even if we stipulated that this particular part
of highlighting was enough of a nuisance to make disabling AUCTeX a
no-brainer _if_ it helped.

[ I'd suggest to move this discussion to <emacs-devel@gnu.org>.

  Summary: In Emacs TeX-mode (textmodes/tex-mode.el), there's no
  option to suppress the raise/lowering of superscripts and
  subscripts.  In AUCTeX, we used tex-mode.el's code, but added
  options to turn off this feature.

I'd be willing to port AUCTeX's customization options ([1], code
written by me) to tex-mode.el.  Any objections?  Stefan?

(If it's okay to install this patch, should it go to the Emacs 22
branch?)

A replacement for the hard-codes values, but that's obvious, isn't it?
Probably I didn't understand your question.  Could you be more
specific, please?

Bye, Reiner.

Well, supposedly you/someone replaced those values by different ones, right?
So how did they differ?  Did only the 0.3 ever change or sometimes the whole
thing?  Did it always change symmetrically? ...

I mean the above variable can be used to make super/subscript display in
very wild ways, so I'm wondering if is a feature or a misfeature.

Personally, I changed them to -0.1/0.1.  I don't know what others do.
But I think asymmetrical values are plausible.

I've installed a simplified version.  Feel free to modify it.

Bye, Reiner.

The value 0.3 was chosen pretty arbitrarily.  Maybe 0.2 would be
a better default.  In my case 0.1 seems too small (it move it by just
1 pixel, which looks more like a display bug than a feature).

Sorry!

In Emacs's builtin tex-mode, there's no config var to do that.
You can do it with the following hack:

(eval-after-load "tex-mode" '(fset 'tex-font-lock-suscript 'ignore))

In AUCTeX (and Emacs-CVS thanks to AUCTeX's maintainer) you can do it by
customizing some faces and vars (e.g. superscript face and
tex-font-script-display var or something like that).
