If you have been using the screen sharing in Zoom you might not be aware that there is a feature that allows you to annotate what you are screen sharing. This means you can add text, shapes, lines, arrows or even draw freehand.
You can even use spotlight so that it is easier to see the mouse pointer giving it a laser pointer type of effect called spotlight or add an arrow to the mouse pointer. Both make it easier to see what you are referring to.
One of my favourites in spotlight is the vanishing pen, this is a new feature and it allows you to draw freehand and when you have finished drawing it slowly disappears.
Here is a video I made that shows you how it works.
