If you’ve used Photoshop for any length of time, you no doubt use layers fairly extensively. They’re a great way to compose a design, because they let you edit and move design elements independently of each other. (If you’re new to layers in Photoshop, take a look at our Introduction to layers tutorial.)
Of course, to edit and manipulate a layer, you need to select it. Sometimes you want to select more than one layer at once. And sometimes, if your document has lots of layers, you want to select a layer quickly by clicking it in the document window. This tutorial walks you through all these techniques, and more, and explores the myriad ways of selecting layers in Photoshop.
