I took a quick look at the instructions. What you will have to do is look into the mouse functions and get the coordinates for the mouse and check to see which button the mouse is in on your own. Then draw text in your text area.
Since this is a word Doc can I assume you are on a windows platform? Its a shame they don't use a standard set of libraries for drawing this stuff. I remember doing this in school and we were using macs to do our programing and at the time I had a windows machine. So I was forced to do all my programs that required graphics at school labs instead of my home PC. Ok enough of my rant
