auctex: Verbatim content
3.1.4 Verbatim macros and environments
--------------------------------------
Usually it is not desirable to have content to be typeset verbatim
highlighted according to LaTeX syntax. Therefore this content will be
fontified uniformly with the face 'font-latex-verbatim-face'.
font-latex differentiates three different types of verbatim
constructs for fontification. Macros with special characters like | as
delimiters, macros with braces, and environments. Which macros and
environments are recognized is controlled by the variables
'LaTeX-verbatim-macros-with-delims',
'LaTeX-verbatim-macros-with-braces', and 'LaTeX-verbatim-environments'
respectively.
