22.6 Font Lock Mode
===================
“Font Lock mode” is a buffer-local minor mode that automatically
attaches ‘face’ properties to certain parts of the buffer based on their
syntactic role. How it parses the buffer depends on the major mode;
most major modes define syntactic criteria for which faces to use in
which contexts. This section explains how to customize Font Lock for a
particular major mode.
Font Lock mode finds text to highlight in two ways: through syntactic
parsing based on the syntax table, and through searching (usually for
regular expressions). Syntactic fontification happens first; it finds
comments and string constants and highlights them. Search-based
fontification happens second.
