Mac – good hotkey cheatsheet for using Latex in Emacs

emacslatex

Is there a good hotkey cheatsheet for using Latex in Emacs? A few minutes of googling didn't turn up anything.

I don't think the TeX mode shipped with Emacs has a cheatsheet (or a 'Refcard' as they're often called in the Emacs world). The closest thing around for AucTeX is its fine manual (PDF here, the quickstart stuff begins on about p. 18). Also note, RefTeX, a full featured citation manager for your BibTeX database (docs here). My own favorite citation manager is the slimmer Ebib.

Another great Emacs-Latex tool is org-mode. It works as a mode for the efficient outlining, writing, and editing of documents in its own lightweight markup syntax. This can then be converted to a few different formats, including LaTeX. Many of us do our writing in org-mode (which does have a cheat sheet, here) and then convert it to LaTeX. Hard stuff may have to touched up by hand in LaTeX, but org gets the basics done nicely, and the 'basics' even do a pretty good job at things like tables, math, poetry, document structure, etc.

Mac – Word count for LaTeX within emacs

(defun latex-word-count ()
  (interactive)
  (shell-command (concat "/usr/local/bin/texcount.pl "
                         ; "uncomment then options go here "
                         (buffer-file-name))))

You may opt to put texcount.pl somewhere other than /usr/local/bin, just modify the code as appropriate if you do. This creates a new command "M-x latex-word-count", which will run texcount.pl on the current file (it will give the wrong result if you have not saved the file though). You can remove the semicolon and replace the filler text with any command line arguments you want to use, if any. You can bind this to a keyboard command with something like this in your .emacs:

(define-key latex-mode-map "\C-cw" 'latex-word-count)

The page which describes how to install texcount is here: texcount faq. Short version:

sudo cp texcount.pl /usr/local/bin/texcount.pl

or alternatively you could do as they recommend and simply name it texcount, and update the code appropriately.

Hmmm...An ugly and not imperfect solution:

(define-key org-mode-map (kbd "$") (lambda ()
                                     (interactive)
                                     (insert "$")
                                     (save-excursion
                                       (left-char 1)
                                       (if (org-inside-LaTeX-fragment-p)
                                           (progn
                                             (right-char 2)
                                             (org-preview-latex-fragment))))))

Anyway, it works on some degree.
