auctex: Font Locking
3.1 Font Locking
================
Font locking is supposed to improve readability of the source code by
highlighting certain keywords with different colors or fonts. It
thereby lets you recognize the function of markup code to a certain
extent without having to read the markup command. For general
information on controlling font locking with Emacs' Font Lock mode, see
Font Lock Mode (emacs)Font Lock.
-- User Option: TeX-install-font-lock
Once font locking is enabled globally or for the major modes
provided by AUCTeX, the font locking patterns and functionality of
font-latex are activated by default. You can switch to a different
font locking scheme or disable font locking in AUCTeX by
customizing the variable 'TeX-install-font-lock'.
Besides font-latex AUCTeX ships with a scheme which is derived from
Emacs' default LaTeX mode and activated by choosing
'tex-font-setup'. Be aware that this scheme is not coupled with
AUCTeX's style system and not the focus of development. Therefore
and due to font-latex being much more feature-rich the following
explanations will only cover font-latex.
In case you want to hook in your own fontification scheme, you can
choose 'other' and insert the name of the function which sets up
your font locking patterns. If you want to disable fontification
in AUCTeX completely, choose 'ignore'.
font-latex provides many options for customization which are
accessible with 'M-x customize-group RET font-latex RET'. For this
description the various options are explained in conceptional groups.
