Icon Maker is a simple Canvas tool that allows you to create icons when authoring content in the Rich Content Editor. The Icon Maker is accessed within the Editor (Announcements, Assignments, Discussions, Pages, Classic Quizzes, and the Syllabus). The icons you create can be re-used again and again. Just having text inside a shape with no icon can be useful, too.
