In order to drag-select multiple layers, select the Move tool and check the Auto-Select option in the Options bar. Click and drag over objects with the Move tool (in the image area) to select the layers. This method works well if you have multiple objects (layers) and a Background. Otherwise, because you have the Auto Select feature turned on, clicking in the image area will select the first layer that you click on and begin to move it instead of selecting additional objects (layers). Note: because a Background is locked by default, it is impossible to select and therefore skipped by the Auto Select Feature. So, if you have layers that you do not want to auto select, lock them. If you prefer to keep the Auto Select Layer unchecked (off), with the Move tool selected, you can use the keyboard shortcut Command (Mac) / Control (Win) to temporarily turn on the auto select functionality.
