# Commutative diagrams and other symbols in org-mode

Recently, I started using `emacs` and I found `org-mode`. I like its concept, but I'm having a lot of troubles for note-taking in LaTeX.

For instance, when I try to put the symbol `\$\varinjlim\$` it simply doesn't show anything, even if I try to include the package using `#+LATEX_HEADER`.

Another problem is that I don't have any idea about how I can use a commutative diagrams package (like the package `diagrams`) in `org-mode`.
