After you install CraftyCursor, you may need to refresh your Chrome browser before it will work. Click on the CraftyCursor icon in the upper right of your screen when you are ready to use it.
You can set your color using the drop down and then click "Start highlighting". Now you will get a highlighted circle around your cursor to help your audience track with your mouse movements.
To stop highlighting, simply click on the CraftyCursor icon again and click "Stop highlighting".
