blink-cursor-mode is an interactive compiled Lisp function in `
It is bound to <menu-bar> <options> <blink-cursor-mode>.
(blink-cursor-mode &optional ARG)
Toggle cursor blinking (Blink Cursor mode).
With a prefix argument ARG, enable Blink Cursor mode if ARG is
positive, and disable it otherwise. If called from Lisp, enable
the mode if ARG is omitted or nil.
If the value of `blink-cursor-blinks' is positive (10 by default),
the cursor stops blinking after that number of blinks, if Emacs
gets no input during that time.
See also `blink-cursor-interval' and `blink-cursor-delay'.
This command is effective only on graphical frames. On text-only
terminals, cursor blinking is controlled by the terminal.
