address@hidden selective undo
address@hidden C-u C-x u
+  Ordinary undo applies to all changes made in the current buffer.  You
+can also perform @dfn{selective undo}, limited to the current region
+(@pxref{Mark}).
+
+  To do this, specify the region you want, then run the @code{undo}
+command with a prefix argument (the value does not matter): @kbd{C-u
+C-x u} or @kbd{C-u C-_}.  This undoes the most recent change in the
+region.  To undo further changes in the same region, repeat the
address@hidden command (no prefix argument is needed).  In Transient Mark
+mode (@pxref{Transient Mark}), any use of @code{undo} when there is an
+active region performs selective undo; you do not need a prefix
+argument.
