Click and drag the mouse or use a stylus to draw on the Canvas. Any materials on Canvas can be drawn on, including graphs, pictures and videos.
To erase your drawing on the Canvas, select the “Erase” button next to the drawing button.
A white circle will appear that will erase anything it hovers over. Drag the circle around to erase drawings on Canvas.
