Annotations are text boxes that are linked directly to a specific object. They are useful because once attached, they move with their host objects. Only one annotation may be added to a given link.
Adding Annotations

Dragging the crosshairs to stretch the rectangle to a certain shape will have no consequence on the actual shape. The box will always snap directly around the text after clicking outside the box.
