Crop by click and dragging

In crop mode the area is made small enough, one can then click and drag over the area desired. How can this be done without first having to click and dragging the handles to reduce the selected area?

Could you maybe rephrase your question please. Not sure I understand correctly.

I would expect you to drag the handles to the area you desire that remains. or you click on “Free” at the bottom/middle below the picture and you have standard presets, maybe thats what you’re looking for.
