Commands to move point affect the value of point for the selected Emacs

@kindex C-Mouse-2 @r{(scroll bar)}
You can split a window horizontally or vertically by clicking
-@kbd{C-Mouse-2} in the mode line or the scroll bar. The line of
-splitting goes through the place where you click: if you click on the
-mode line, the new scroll bar goes above the spot; if you click in the
-scroll bar, the mode line of the split window is side by side with your
+@kbd{C-Mouse-2} in the mode line or the scroll bar. (This does not
+work in scroll bars implemented by X toolkits.) The line of splitting

+bar, the mode line of the split window is side by side with your
click.

@findex other-window
To select a different window, click with @kbd{Mouse-1} on its mode
line. With the keyboard, you can switch windows by typing @kbd{C-x o}

+(@code{other-window}). That is an @kbd{o}, for ``other,'' not a zero.
When there are more than two windows, this command moves through all the
windows in a cyclic order, generally top to bottom and left to right.
After the rightmost and bottommost window, it goes back to the one at

heights of all the windows in the selected frame.

+@cindex undoing window configuration changes
+@cindex window configuration changes, undoing
+ @kbd{M-x winner-mode} is a global minor mode that records the
+changes in the window configuration (i.e. how the frames are
+partitioned into windows), so that you can ``undo'' them. To undo,
+use @kbd{C-x left} (@code{winner-undo}). If you change your mind
+while undoing, you can redo the changes you had undone using @kbd{C-x
+right} (@code{M-x winner-redo}). Another way to enable Winner mode is
+by customizing the variable @code{winner-mode}.

+@cindex Windmove package
+@cindex directional window selection

+ The Windmove commands move directionally between neighbouring windows in
+a frame. @kbd{M-x windmove-right} selects the window immediately to the
+right of the currently selected one, and similarly for the ``left,'' ``up,''
+and ``down'' counterparts. @kbd{M-x windmove-default-keybindings} binds
+these commands to @kbd{S-right} etc. (Not all terminals support shifted
+arrow keys, however.)

+ @kbd{M-x scroll-all-mode} provides commands to scroll all visible
+windows together. You can also turn it on by customizing the variable
+@code{scroll-all-mode}. The commands provided are @kbd{M-x
+scroll-all-scroll-down-all}, @kbd{M-x scroll-all-page-down-all} and
+their corresponding ``up'' equivalents. To make this mode useful,
+you should bind these commands to appropriate keys.
