Interact with an already added whiteboard element to move, change, or delete it. To select an object, click on it once with the pointer. To deselect an object, click on an empty spot on the canvas, select another tool, or select another object.
You can also select multiple objects by clicking and holding then dragging the pointer to define a rectangular area. When you select multiple objects, you can group them into one object to manipulate the group of objects you have to select a large grouped object instead.
