Semanas atrás, encontrei esta resposta para link em tex.stackexchange.com.
"Leo2007" descreve como inserir * .tex-templates em um buffer do Emacs. Eu não consegui descobrir, como fazer isso funcionar e decidi perguntar na lista de discussão autex , mas não obteve resposta por três semanas. Então talvez você possa me ajudar:
"Leo2007" apresentou o arquivo minibuffer-choose.el , que deve permitir inserir um
modelo em um documento rapidamente. Siga o link Nr. 1 acima e você verá um
imagem bastante convincente.
Infelizmente, não entendo como usá-lo. Eu peguei o arquivo
minibuffer-choose.el daqui: link
(Eu adicionei abaixo).
Eu fiz uma compilação de byte, coloquei onde o emacs pode encontrá-lo e adicionei 3 linhas ao meu arquivo .emacs:
(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?

Eu odeio oferecer outra opção, mas se você estiver procurando por recursos de inserção automática, procure em yasnippet em vez disso, que é poderoso perverso e se tornando o padrão-de-facto para as inserções do emacs. Eles já têm um monte de snippets de látex que as pessoas vêm trabalhando, mas adicionando novos é muito fácil para qualquer coisa especial que você precisa para si mesmo.
