set-cursor-color
set-cursor-color is an interactive compiled Lisp function in `frame.el
'.
(set-cursor-color COLOR-NAME)
Set the text cursor color of the selected frame to COLOR-NAME.
When called interactively, prompt for the name of the color to use.
This works by setting the `cursor-color' frame parameter on the
selected frame.
You can also set the text cursor color, for all frames, by
customizing the `cursor' face.
