Tip of the Week: Learn standard copy edit marks.
If you go here to the Chicago Manual of Style, you will find a page of standard copy edit marks.

Nothing is more confusing than trying to explain to someone what you think a work needs without using standard marks. So learn them. Love them. Make them your own.
