I have asked this very basic question before but never received an answer. So I am trying again.
Is there a way to draw a circular (or rectangular) selection from a centre point? With the shape tool and all transformations this is done in a consistent manner by holding down the Cmd key. With selections the Cmd key is (inconsistently) elsewhere assigned. Since most of my selections end up being converted to a mask layer I have a work around by drawing a shape layer and then rasterising to a mask and dragging it in the layers palette to where I need it. But it's irritating and seems rather unnecessary. Am I missing something embarrassingly obvious here? :unsure:
