+@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}.)
@findex dired-copy-filename-as-kill
The @kbd{w} command (@code{dired-copy-filename-as-kill}) puts the
names of the marked (or next @var{n}) files into the kill ring, as if
-you had killed them with @kbd{C-w}.
+you had killed them with @kbd{C-w}. The names are separated by a space.
The main purpose of this command is so that you can yank the file
names into arguments for other Emacs commands. It also displays what
was pushed onto the kill ring, so you can use it to display the list
of currently marked files in the echo area. With a zero prefix
-argument @var{n}=0, this uses the absolute file name of each marked
-file. With just @kbd{C-u} as the prefix argument, it uses the
-relative file name of each marked file. As a special case, if no
-prefix argument is given and point is on a directory headerline,
-@kbd{w} gives you the name of that directory without looking for
-marked files.

+argument, this uses the absolute file name of each marked file. With
+just @kbd{C-u} as the prefix argument, it uses file names relative to
+the Dired buffer's default directory. (This can still contain slashes
+if in a subdirectory.) As a special case, if point is on a directory
+headerline, @kbd{w} gives you the absolute name of that directory.
+Any prefix argument or marked files are ignored in this case.
+
+@findex dired-compare-directories
+ The command @kbd{M-x dired-compare-directories} is used to compare
+the current Dired buffer with another directory. It marks all the files
+that are ``different'' between the two directories. It puts these marks
+in all Dired buffers where these files are listed, which of course includes
+the current buffer.
+
+ The default comparison method (used if you type @key{RET} at the
+prompt) is to compare just the file names---each file name that does
+not appear in the other directory is ``different''. You can specify
+more stringent comparisons by entering a Lisp expression, which can
+refer to the variables @code{size1} and @code{size2}, the respective
+file sizes; @code{mtime1} and @code{mtime2}, the last modification
+times in seconds, as floating point numers; and @code{fa1} and
+@code{fa2}, the respective file attribute lists (as returned by the
+function @code{file-attributes}). This expression is evaluated for
+each pair of like-named files, and if the expression's value is
+non-@code{nil}, those files are considered ``different''.
+
+ For instance, @code{M-x dired-compare-directories @key{RET} (>
+mtime1 mtime2) @key{RET}} marks files newer in this directory than in
+the other, and marks files older in the other directory than in this
+one. It also marks files with no counterpart, in both directories, as
+always.
+
+@cindex drag and drop, Dired
On the X window system, Emacs supports the ``drag and drop''
protocol. You can drag a file object from another program, and drop
it onto a Dired buffer; this either moves, copies, or creates a link
