Transforming encompasses moving, rotating, reflecting, scaling, and shearing objects. You can transform objects using the Transform panel, Object > Transform commands, and specialized tools. You can also perform many types of transformations by dragging the bounding box for a selection.
Sometimes you may want to repeat the same transformation several times, especially when you are copying objects. The Transform Again command in the Object menu lets you repeat a move, scale, rotate, reflect, or shear operation as many times as you want, until you perform a different transform operation.
