[MonoDevelop] Syntax Highlighting - operators:

[mikey at lawtechgold.com]

Using MonoDevelop 3.0.3.2.

I set up a custom syntax highlighting scheme. There are SO MANY setting
but I finally got it the way I like, except for operators: ".", ";",
"=", "+", etc. 

Every IDE I've used had an option to show them in a specific designated
color - very important to me when I scan code. But I cannot find the
right option setting in MonoDevelop. How do I do this?
