mouse button, and sets the mark at the other end of that range. Or you
can click mouse button three, which sets the mark at point (like
@kbd{C-@key{SPC}}) and then moves point where you clicked (like
-@kbd{Mouse-1}). Both of these methods copy the region into the kill
+@kbd{Mouse-1}).

+ Using the mouse to mark a region copies the region into the kill
ring in addition to setting the mark; that gives behavior consistent

Most commands that operate on the text in the region have the word
@code{region} in their names.
-@node Selective Undo
-@section Selective Undo

-@cindex selective undo
-@kindex 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
-@code{undo} 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.

@node Marking Objects
@section Commands to Mark Textual Objects
marks @var{n} paragraphs, running back form the one surrounding point.
In that last case, point moves forward to the end of that paragraph,
and the mark goes at the start of the region. Repeating the @kbd{M-h}
-command extends the region, just as with @kbd{M-@@} and @kbd{C-M-@@}.
+command extends the region to subsequent paragraphs.
@kbd{C-M-h} (@code{mark-defun}) similarly puts point before, and the
mark after, the current (or following) major top-level definition, or
-defun (@pxref{Moving by Defuns}). Repeating @kbd{C-M-h} also extends
-the region.
+defun (@pxref{Moving by Defuns}). Repeating @kbd{C-M-h} extends
+the region to subsequent defuns.
@kbd{C-x C-p} (@code{mark-page}) puts point before the current page,
and mark at the end (@pxref{Pages}). The mark goes after the
