Some window systems and window managers direct keyboard input to the
window object that the mouse is in; others require explicit clicks or
commands to @dfn{shift the focus} to various window objects. Either

+way, Emacs automatically keeps track of which frame has the focus. To
+switch to a different frame from a Lisp function, call
+@code{select-frame-set-input-focus}.
Lisp programs can also switch frames ``temporarily'' by calling the
function @code{select-frame}. This does not alter the window system's
concept of focus; rather, it escapes from the window manager's control
until that control is somehow reasserted.
-When using a text-only terminal, only the selected terminal frame is
-actually displayed on the terminal. @code{switch-frame} is the only way
-to switch frames, and the change lasts until overridden by a subsequent
-call to @code{switch-frame}. Each terminal screen except for the
-initial one has a number, and the number of the selected frame appears
-in the mode line before the buffer name (@pxref{Mode Line Variables}).
+When using a text-only terminal, only one frame can be displayed at a
+time on the terminal, so after a call to @code{select-frame}, the next
+redisplay actually displays the newly selected frame. This frame
+remains selected until a subsequent call to @code{select-frame} or
+@code{select-frame-set-input-focus}. Each terminal frame has a number
+which appears in the mode line before the buffer name (@pxref{Mode
+Line Variables}).

+@defun select-frame-set-input-focus frame
+This function makes @var{frame} the selected frame, raises it (should
+it happen to be obscured by other frames) and tries to give it the X
+server's focus. On a text-only terminal, the next redisplay displays
+the new frame on the entire terminal screen. The return value of this
+function is not significant.

@c ??? This is not yet implemented properly.
@defun select-frame frame
the next time the user does something to select a different frame, or
until the next time this function is called. The specified @var{frame}
becomes the selected frame, as explained above, and the terminal that
-@var{frame} is on becomes the selected terminal.
+@var{frame} is on becomes the selected terminal. This function
+returns @var{frame}, or @code{nil} if @var{frame} has been deleted.
In general, you should never use @code{select-frame} in a way that could
switch to a different terminal without switching back when you're done.

@defun x-set-cut-buffer string &optional push
+@anchor{Definition of x-set-cut-buffer}
This function stores @var{string} into the first cut buffer (cut buffer
0). If @var{push} is @code{nil}, only the first cut buffer is changed.
If @var{push} is non-@code{nil}, that says to move the values down
(All color displays can do this.)
@end defun
-@anchor{Display Face Attribute Testing}
@defun display-supports-face-attributes-p attributes &optional display
+@anchor{Display Face Attribute Testing}
@tindex display-supports-face-attributes-p
This function returns non-@code{nil} if all the face attributes in
@var{attributes} are supported (@pxref{Face Attributes}).
