If you Option (Alt)-click on any ICON (not button) in the Control palette, a dialog will open to enter all of your specifications. For instance, if you select an object with your Selection tool (V) and Option (Alt)-click on the icon for Rotation Angle, a dialog will open to enter an Angle. The dialog usually offers more options. With Rotate, the dialog includes a Copy button. If you need to make a rotated Copy of an object, this is a fast way to do it.
