Copying attributes

The Attribute Dropper tool  lets you copy the fill, stroke, and effect attributes from one object in your document to another. In effect, this copies all of the formatting you can set in the Properties panel in one movement. To copy these attributes from one object to another, click the fill or stroke area of the first object, then, while you hold down the mouse button, drag the Attribute Dropper tool to the second object. Release the mouse button over the fill or stroke area of the second object. If the second object has no fill or stroke color, then release the mouse button while the tool is over the path itself.

Dragging the Attribute Dropper from the object on the left to the object on the right copies the fill, stroke, and live effects (in this case, a Gaussian Blur) to the second object.
