 @cindex 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 region.
-
-  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.
address@hidden C-u C-/
+  When there is an active region, any use of @code{undo} performs
address@hidden undo}, undoing the most recent change within the
+region, instead of the entire buffer.  However, when Transient Mark
+mode is off (@pxref{Persistent Mark}), @kbd{C-/} always operates on
+the entire buffer, ignoring the region.  In this case, you can perform
+selective undo by supplying a prefix argument to the @code{undo}
