+ This section describes Dired commands which alter file names in a
+systematic way.
+
+ Like the basic Dired file-manipulation commands (@pxref{Operating on
+Files}), the commands described here operate either on the next
+@var{n} files, or on all files marked with @samp{*}, or on the current
+file. (To mark files, use the commands described in @ref{Marks vs
+Flags}.)
+
+ All of the commands described in this section work
+@emph{interactively}: they ask you to confirm the operation for each
+candidate file. Thus, you can select more files than you actually
+need to operate on (e.g., with a regexp that matches many files), and
+then refine the selection by typing @kbd{y} or @kbd{n} when the
+command prompts for confirmation.
