AUCTeX is an extensible package for writing and formatting TeX files in GNU Emacs and XEmacs. It supports many different TEX macro packages, including AMS-TEX, LaTeX, Texinfo, ConTEXt, and docTeX (dtx files). AUCTeX includes preview-latex which makes LaTeX a tightly integrated component of your editing workflow by visualizing selected source chunks (such as single formulas or graphics) directly as images in the source buffer.

Emacs 24 and ELPA
If you install AUCTeX via ELPA in Emacs 24 the basic setup listed above is not necessary. AUCTeX just works out of the box (at least on Linux).
Switch all fonts to monospace
AUCTeX's default fontification uses several different text sizes. If this behavior is not desired, it may be turned off by the following:
(setq font-latex-fontify-script nil) (setq font-latex-fontify-sectioning 'color) ; modify Beamer as well (custom-set-faces '(font-latex-slide-title-face ((t (:inherit font-lock-type-face))))) (font-latex-update-sectioning-faces)
which should be loaded by a hook.
(setq TeX-PDF-mode t)
Configure view program
(setq TeX-view-program-selection '((output-dvi "DVI Viewer") (output-pdf "PDF Viewer") (output-html "HTML Viewer"))) ;; this example is good for OS X only (setq TeX-view-program-list '(("DVI Viewer" "open %o") ("PDF Viewer" "open %o") ("HTML Viewer" "open %o")))
