@node Windows, Frames, Buffers, Top
In each frame, at any time, one and only one window is designated as
@dfn{selected within the frame}. The frame's cursor appears in that
window, but the other windows have ``non-selected'' cursors, normally
-less visible. At any time, one frame is the selected frame; and the
-window selected within that frame is @dfn{the selected window}. The
-selected window's buffer is usually the current buffer (except when
-@code{set-buffer} has been used). @xref{Current Buffer}.

-@defvar cursor-in-non-selected-windows
-If this variable is @code{nil}, Emacs displays only one cursor,
-in the selected window. Other windows have no cursor at all.

+At any time, one frame is the selected frame; and the window selected
+within that frame is @dfn{the selected window}. The selected window's
+buffer is usually the current buffer (except when @code{set-buffer}
+has been used). @xref{Current Buffer}.
For practical purposes, a window exists only while it is displayed in
a frame. Once removed from the frame, the window is effectively deleted
@end example
@end defun
+@defun window-full-width-p &optional window
+This function returns non-@code{nil} if @var{window} is as wide as
+the frame that contains it; otherwise @code{nil}.
+If @var{window} is @code{nil}, the function uses the selected window.
+@end defun

@defun window-edges &optional window
This function returns a list of the edge coordinates of @var{window}.
If @var{window} is @code{nil}, the selected window is used.
@cindex saving window information
A @dfn{window configuration} records the entire layout of one
-frame---all windows, their sizes, which buffers they contain, what
-part of each buffer is displayed, and the values of point and the
-mark; also their fringes, margins, and scroll bar settings. It also

+those buffers are scrolled, and their values of point and the mark;
+also their fringes, margins, and scroll bar settings. It also
includes the values of @code{window-min-height},
-@code{window-min-width} and @code{minibuffer-scroll-window}. An
-exception is made for point in the selected window for the current
-buffer; its value is not saved in the window configuration.
+@code{window-min-width} and @code{minibuffer-scroll-window}. As a
+special exception, the window configuration does not record the value
+of point in the selected window for the current buffer.
You can bring back an entire previous layout by restoring a window
configuration previously saved. If you want to record all frames
