There’s more to the Rectangular Marquee tool than meets the eye. Select it from the Tools panel, and then just click the appropriate button on the tool options bar to create a new selection, add to a selection, delete a selection, or intersect with another selection, as shown in Figure A. To smooth the edges of a selection, enter a pixel value in the Feather text box. Your only other option is to choose Normal, Fixed Size, or Fixed Aspect Ratio from the Style pop-up menu. Choose Normal to create a random selection, choose Fixed Size to create a selection of a specific size, or choose Fixed Aspect Ratio to create a selection that maintains its width-to-height proportions, regardless of size.
