Version 4.18.5 of package Cdlatex has just been released in NonGNU ELPA. You can now find it in M-x list-packages RET.
Cdlatex describes itself as: ================================================== Fast input methods for LaTeX environments and math ================================================== More at https://elpa.nongnu.org/nongnu/cdlatex.html ## Summary: Commentary: CDLaTeX is a minor mode supporting fast insertion of environment templates and math stuff in LaTeX. To turn CDLaTeX Minor Mode on and off in a particular buffer, use `M-x cdlatex-mode'. To turn on CDLaTeX Minor Mode for all LaTeX files, add one of the following lines to your .emacs file: (add-hook 'LaTeX-mode-hook #'turn-on-cdlatex) ; with AUCTeX LaTeX mode (add-hook 'latex-mode-hook #'turn-on-cdlatex) ; with Emacs latex mode For key bindings, see further down in this documentation. CDLaTeX requires texmathp.el (which is distributed with AUCTeX) to auto-insert $...$ when needed, so we recommend you install AUCTeX to get this functionality. -------------------------------------------------------------------------- OVERVIEW ======== ## Recent NEWS: [Not provided 🙁]
