(global-font-lock-mode t)
-There are a number of support modes that may be used to speed up Font Lock mode
-in various ways, specified via the variable `font-lock-support-mode'. Where
-major modes support different levels of fontification, you can use the variable
-`font-lock-maximum-decoration' to specify which level you generally prefer.
-When you turn Font Lock mode on/off the buffer is fontified/defontified, though
-fontification occurs only if the buffer is less than `font-lock-maximum-size'.
-
-For example, to specify that Font Lock mode use use Lazy Lock mode as a support
-mode and use maximum levels of fontification, put in your ~/.emacs:
-
- (setq font-lock-support-mode 'lazy-lock-mode)
- (setq font-lock-maximum-decoration t)
+Where major modes support different levels of fontification, you can use
+the variable `font-lock-maximum-decoration' to specify which level you
+generally prefer. When you turn Font Lock mode on/off the buffer is
+fontified/defontified, though fontification occurs only if the buffer is
+less than `font-lock-maximum-size'.
To add your own highlighting for some major mode, and modify the highlighting
selected automatically via the variable `font-lock-maximum-decoration', you can
The above is the default behavior of `font-lock-mode'; you may specify
your own function which is called when `font-lock-mode' is toggled via
`font-lock-function'. "
