There are two blocks of tools you can use to make annotations - the Simple shapes, and the Polygon shapes.

Below are the set of tools you can use to draw annotations on slide.

And here is what they look like by default:

For the Point and the three Landmarks, you just have click, and your annotation will be made.

For the resizable shapes e.g. Circle, Line… you click once to start - then choose the size - then click again to finish.

Below are the set of complex tools you can use to draw annotations on slide.

And here you can see how they look when they are finished

1. Multipoint - click your points, when finished, click 'Finish'
2. Polygon - each time you click creates a new angle in your shape. Double click to finish
3. Closed freehand - click and drag - the shape is finished when you release the mouse
4. Compound freehand - click and drag to make a line. When you release, you will be prompted to 'Draw' or 'Finish' which let you draw another line, and finish the shape. Finishing the shape will join up all the lines you have drawn into one shape.
