Weeks ago I found this answer to Most significant reasons that led us to (La)TeX on tex.stackexchange.com.

"Leo2007" describes, how to insert *.tex-templates into a buffer of Emacs. I could not find out, how to make it work and decided to ask on the autex-mailinglist, but got no answer for three weeks. So maybe you can help me:

"Leo2007" presented the file minibuffer-choose.el, which should allow to insert a template into one's document quickly. Follow the link Nr. 1 above and you will see a quite convincing picture.

Unfortunately I do not understand how to use it. I got the the file minibuffer-choose.el from here: http://paste.lisp.org/display/113728 (I added it below).

I made a byte-compile, put it where emacs can find it and added 3 lines to my .emacs-file:

(require 'minibuffer-choose)
(let ((files (directory-files "~/Emacs/Vorlagen" t "[a-z]+")))
  (minibuffer-choose "Choose: " files 'file-name-nondirectory nil 'alpha))

But how do I use it?

This question came from our site for users of TeX, LaTeX, ConTeXt, and related typesetting systems.

I hate to offer you another choice instead, but if you're looking for auto-insertion capabilities you might look into yasnippet instead which is wicked powerful and becoming the defacto-standard for emacs insertions. They already have a bunch of latex snippets that people have been working on, but adding new ones is quite easy for anything special you need for yourself.
