Photoshop: Need draggable Clone Source rotate key command
To add a rotate to the existing draggable key command, that does not take your preview brush off the art. This way you can make precise alignments. There is a key command of SHIFT OPTION > or <, but that is much to slow to be useful, even with my OS key repeat rate set to fast.
This would resolve an earlier post I have of rotating the standard oval brush for illustrating shadows, as this suggestion should work for all brushes (clone stamp, healing, brush, pencil, healing).
