When you create a frame while pressing [Shift], the frame will be created in square size. When you press [Option] while creating a frame, the place where you clicked first will be used as the frame center rather than the left upper corner of the frame. You can press [Shift] and [Option] simultaneously to combine both effects. [Esc] cancels the frame creation.
