User Cursors allow you to see where others are when you are working with them in the same board. In your viewport, you will see rectangles representing the viewport of other users. Every participant on the board has their own cursor and name tag, so there’s no more guessing about which part of the content someone is talking about.
To turn on User Cursors, select them from the left hand tool bar of your board or select it from the Conference menu. The icon will have a check mark next to it when the tool is turned on.
