Zooming in iPhoto

Question

Apple Photos

How do I zoom in on a photo in iPhoto? The standard combination of "spread fingers" does not work.

Answer 1

Magic mouse, it looks like nothing.
Click on the photo thumbnail, then click edit, and there is a zoom bar in the lower left corner to the right of the Full Screen button.

Answer 2

If you use Magic mouse, then there is the MouseWizard program. She can definitely add zoom by breeding.
