+ @cindex background syntax highlighting
+   Fontifying large buffers can take a long time.  To avoid large
+ delays when a file is visited, Emacs fontifies only the visible
+ portion of a buffer.  As you scroll through the buffer, each portion
+ that becomes visible is fontified as soon as it is displayed.  The
+ parts of the buffer that are not displayed are fontified
+ ``stealthily'', in the background, i.e.@: when Emacs is idle.  You can
+ control this background fontification, called @dfn{Just-In-Time}, or
+ @dfn{JIT} Font Lock, by customizing various options in the
+ customization group @samp{jit-lock}.  @xref{Specific Customization}.
