You could use LaTeX-math-mode
from the AucTex package. This provides quick completion of common math macros like \alpha
, \sum
, \Sigma
etc. Make sure the package is loaded with the following line in your .emacs
:
(require 'latex)
And then from your org-mode buffer turn on latex-math-mode
with M-x latex-math-mode
. This provides shortcuts for a number of math symbols. You start by entering the backtick symbol "`". The next key will add a LaTeX macro. For example, a
inserts \alpha
, C-_
inserts \inf
, etc. The full list is available on the auctex reference card, and you can add your own shortcuts by customizing the variable LaTeX-math-list
.
Entering two backticks in a row inserts a plain backtick. You can change the prefix key if you don't want to use the backtick - see the customization option LaTeX-math-abbrev-prefix
.
If you have more complex completion needs, you can use company-mode, yasnippet etc. I don't think there is anything special about configuring these for use with org-mode, relative to any other Emacs mode.
