+@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.
