@var{directory} or its subdirectories that contain a match for
@var{regexp}. It works by running the programs @code{find} and
-@code{grep}. See also @kbd{M-x grep-find}, in @ref{Compilation}.
+@code{grep}. See also @kbd{M-x grep-find}, in @ref{Grep Searching}.
Remember to write the regular expression for @code{grep}, not for Emacs.
(An alternative method of showing files whose contents match a given
regexp is the @kbd{% g @var{regexp}} command, see @ref{Marks vs Flags}.)
