It is not easy to find cursor in document. and is it possible give users an option to select cursor type like Line/Block/Underscore, and blinking or not?
You can define your own Style:
choose menu "Customize Schemes...", Dbl-Click Syntax you would like to change,
select Caret (Color; size 1-3), enter for example: size:3; fore:#FF0000.
(thicker than 3 is not possible :-/)
