Although cloning in perspective is most easily accomplished using the Vanishing Point feature, there are several other types of transformations that can be made when cloning using the options in the Clone Source panel. For example, you can choose to offset the cloned information by a certain value, change the width and height, and change the angle. here are the corresponding keyboard shortcuts:
Option (Mac) / Alt (Win) + Shift + left/right arrow keys move the clone source.
Option (Mac) / Alt (Win) + Shift + will rotate the clone source.
Option (Mac) / Alt (Win) + Shift + [ or ] will scale (increase or reduce size) the clone source.
