I'd like to set the behavior of the cropping tool.
I want it to define cropping areas based on...
A fixed, numerical set of pixel dimensions.
A given proportion, e.g., a 9 by 12 area of arbitrary size.
Free size and proportion -- wherever I release the mouse button.
Where can I set that for the cropping tool?
UPDATE / CLARIFICATION
The marquee tool provides this menu, circled below...
But the cropping tool doesn't offer a menu like that...
Does the cropping tool does have these three modes like the marquee tool? If so, where do I set that? How do I tell the cropping tool which mode to use?
