+@defvar blink-cursor-alist
+This variable specifies how to blink the cursor. Each element has the
+form @code{(@var{on-state} . @var{off-state})}. Whenever the cursor
+type equals @var{on-state} (comparing using @code{equal}), Emacs uses
+@var{off-state} to specify what the cursor looks like when it blinks
+``off''. Both @var{on-state} and @var{off-state} should be suitable
+values for the @code{cursor-type} frame parameter.
+
+There are various defaults for how to blink each type of cursor,
+if the type is not mentioned as an @var{on-state} here. Changes
+in this variable do not take effect immediately, because the variable
+is examined only when you specify a cursor type for a frame.
+@end defvar
+
+These frame parameters are semi-obsolete in that they are automatically
+equivalent to particular face attributes of particular faces.
+
+@table @code
+@item font
+The name of the font for displaying text in the frame. This is a
+string, either a valid font name for your system or the name of an Emacs
+fontset (@pxref{Fontsets}). It is equivalent to the @code{font}
+attribute of the @code{default} face.
+
+@item foreground-color
+The color to use for the image of a character. It is equivalent to
+the @code{:foreground} attribute of the @code{default} face.
+
+@item background-color
+The color to use for the background of characters. It is equivalent to
+the @code{:background} attribute of the @code{default} face.
+
+@item mouse-color
+The color for the mouse pointer. It is equivalent to the @code{:background}
+attribute of the @code{mouse} face.
+
+@item cursor-color
+The color for the cursor that shows point. It is equivalent to the
+@code{:background} attribute of the @code{cursor} face.
+
+@item border-color
+The color for the border of the frame. It is equivalent to the
+@code{:background} attribute of the @code{border} face.
+
+@item scroll-bar-foreground
+If non-@code{nil}, the color for the foreground of scroll bars. It is
+equivalent to the @code{:foreground} attribute of the
+@code{scroll-bar} face.
+
+@item scroll-bar-background
+If non-@code{nil}, the color for the background of scroll bars. It is
+equivalent to the @code{:background} attribute of the
+@code{scroll-bar} face.
