Use the Shape Selection tool to select shapes with one click. If you convert a shape into a bitmap element by simplifying the shape layer, the Shape Selection tool will no longer select the shape (use the Move tool instead).
If a layer contains multiple shapes, you can reposition all the shapes together using the Move tool. However, if you want to reposition a specific shape in a layer, you must use the Shape Selection tool.
Click the shape you want to transform, and then drag an anchor to transform the shape.
Select the shape you want to transform, choose Image > Transform Shape, and then choose a transformation command.
If the color of a shape doesn’t change when you pick a new color, check to see if the layer has a layer style (represented by a style icon in the Layers panel). Some layer styles override the base color of a shape.
You can apply effects—such as drop shadows and bevels—to shapes quickly and easily using layer styles. Keep in mind that a layer style is applied to all shapes in a layer. For example, if you apply a drop shadow style to a layer that contains multiple shapes, all of the shapes will display a drop shadow.
