- All the non-minibuffer windows in a frame are arranged in a cyclic
-order. The order runs from the frame's top window, which is at the
-upper left corner, down and to the right, until it reaches the window at
-the lower right corner (always the minibuffer window, if the frame has
-one), and then it moves back to the top. @xref{Cyclic Window Ordering}.

-At any time, exactly one window on any frame is @dfn{selected within the

-frame also selects this window. Conversely, selecting a window for

@cindex selection (for window systems)
-
-The X server records a set of @dfn{selections} which permit transfer of
-data between application programs. The various selections are
-distinguished by @dfn{selection types}, represented in Emacs by
-symbols. X clients including Emacs can read or set the selection for
-any given type.
+@cindex clipboard
+@cindex primary selection
+@cindex secondary selection
+
+ In the X window system, data can be transferred between different
+applications by means of @dfn{selections}. X defines an arbitrary
+number of @dfn{selection types}, each of which can store its own data;
+however, only three are commonly used: the @dfn{clipboard},
+@dfn{primary selection}, and @dfn{secondary selection}. @xref{Cut and
+Paste,, Cut and Paste, emacs, The GNU Emacs Manual}, for Emacs
+commands that make use of these selections. This section documents
+the low-level functions for reading and setting X selections.
@deffn Command x-set-selection type data
-This function sets a ``selection'' in the X server. It takes two
-arguments: a selection type @var{type}, and the value to assign to it,
-@var{data}. If @var{data} is @code{nil}, it means to clear out the
-selection. Otherwise, @var{data} may be a string, a symbol, an integer
-(or a cons of two integers or list of two integers), an overlay, or a
-cons of two markers pointing to the same buffer. An overlay or a pair
-of markers stands for text in the overlay or between the markers.
-
-The argument @var{data} may also be a vector of valid non-vector
-selection values.
-
-Each possible @var{type} has its own selection value, which changes
-independently. The usual values of @var{type} are @code{PRIMARY},
-@code{SECONDARY} and @code{CLIPBOARD}; these are symbols with upper-case
-names, in accord with X Window System conventions. If @var{type} is
-@code{nil}, that stands for @code{PRIMARY}.
+This function sets an X selection. It takes two arguments: a

+upper-case names, in accord with X Window System conventions. If
+@var{type} is @code{nil}, that stands for @code{PRIMARY}.

clipboard as empty.
-@defopt x-select-enable-clipboard
-If this is non-@code{nil}, the Emacs yank functions consult the

-the clipboard as well as the primary selection. Otherwise they do not
