Crop tool - where is commit?

I am using PSE12.  The help regarding committing a crop states "Click the green Commit button located in the lower-right corner of the marquee, or double-click the bounding box to finish the cropping. To cancel the cropping operation, click the red Cancel button or press Esc."

I cannot locate the button.  Double clicking on the bounding box simple erases it (bounding box disappears).  What am i missing?
