Dreaming in XEmacs

[Joe Corneli <jcorneli@mail.ma.utexas.edu>]

Hello --

Here are a couple of things I'd really like to see -- if they
exist, I'd like to know about them, if not, it would be interesting
to hear some discussion/hints about how to write the necessary code.

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
Item 1.  Real-time array neatener for XEmacs
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

I use XEmacs to write TeX code and when I encounter an array (especially a
big one) I usually begin to feel a bit of a panic.  Wouldn't it be nice if
XEmacs kept the &'s lined up vertically, so that this took 15 seconds or
less to write (instead of a minute or so of tedious fiddling):

$$
\begin{array}{ccc}
0          & 1     & \alpha \\
\mathbf{F} & \beta & 1      \\
0          & 1     & \gamma \\
\end{array}
$$

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
Item 2. Small font size for arrays.
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

When I started using XEmacs a lot, I set up my configuration file to use a
fairly big default font, 22pt I think -- in general, this seems to be the
best way to use my "screen real estate".  But when I come to an array I
would prefer to switch back to 10pt or so.  Presumably this is pretty easy
to set up (whatever file makes \emph{italic} italic and $\alpha$ a
different color and $$\alpha$$ a different color still can presumably be
edited to support this).  Any clues about the code (I don't want to mess
this particular file up!)?


Thanks --
