The lightning completion package and the ultratex package are
distributed together. If you just want lightning completion, then you
just need the file "light.el" from the lisp directory, and optionally
the documentation "light.texi" from the texi directory.



Lightning completion package
----------------------------------
(Version 0.90 of 2022/07/28)

The lightning completion package lets Emacs use "dynamic completion"
on any number of things.  By dynamic completion, I mean that you don't
need to hit the tab key to initiate completion: once it is on, it
stays on until there is a unique completion or it is turned off.  This
can be disconcerting at first, but once you get used to it, it is
quite useful--especially when used with commands like find-file or
describe-function.

Please read the documenation (in the texi directory) for more
information.

The lightning completion package was written by Mark Haiman and Nick
Reingold, then modified by John Palmieri (including getting everything
to work with Emacs 19).  Many suggestions were made by various people
at MIT, Yale, and elsewhere.

Ultra-TeX package
----------------------------------
(Version 0.90 of 2022/07/28)

Ultra-TeX is an Emacs mode for editing LaTeX files (well, for editing
TeX files in general, but it has been written very much with LaTeX in
mind).  It features dynamic completion on TeX commands (described
below), as well as a few other things.  For instance, it has an
intelligent math mode; by looking at the cursor position, it decides
whether you are in a math environment or not, and reacts accordingly
(e.g., if you hit the key sequence to start boldface type, it inserts
either "\mathbf" or "\textbf" depending on whether you're in math
mode).  It has other features; read the documentation for a full
description.

One of the main features of Ultra-TeX is dynamic completion on TeX
commands (although you can run Ultra-TeX without it, and some people
choose to do so).  This means that when you hit a backslash "\", Emacs
immediately tries to complete, and it continues to try to complete
after each character you type.  For example, if Ultra-TeX only knows
about the commands \sqrt[]{}, \subsection{}, and \paragraph{}, then if
you hit "\" followed by "p", Ultra-TeX inserts \paragraph{} (because
that is the only valid completion starting "\p").  If you type "\s",
then it waits for the next character; then typing "q" results in
"\sqrt[]{}", typing "u" results in "\subsection{}", and typing
anything else results in a beep.  Much of this behavior can be
customized: you can turn off dynamic completion altogether; you can
have a delay before it tries to complete (so you don't have to worry
about needing to keep an eye on the screen--you can type as much or as
little of, say, "\subsection{}", and if you want, stop and wait for it
to complete the rest, or hit the SPC key and force it to complete the
rest); with the delay you can turn off the beep for non-recognized
completions, so you can type "\sigma" without getting beeped at.

The first version of Ultra-TeX was written by Mark Haiman, then
rewritten by him and Nick Reingold.  John Palmieri then made various
modifications, including getting everything to work with Emacs 19.
Many suggestions were made by various people at MIT, Yale, and
elsewhere.
