Using the Layers window
The Layers window displays a list of the layers in the current document. You can see basic information about all the document’s layers at a glance, and you can click an item in the list to select the corresponding layer or double-click an item to access the layer’s properties.
To open the Layers window: On the View menu, go to the Panel group, and then select Layers.
The Layers window
The layer list includes the name, Z-index, and visibility attribute of each layer. If a layer is a child of another layer (that is, its layer markA small icon, visible only in Edit mode, that marks the location of a layer tag in the document. is inside another layer), the name of the layer will appear indented under the name of its parent. Click an item in the list to select the corresponding layer. Double-click an item to open the Layer Properties dialog box for the corresponding layer.
If you select the Layers snap to each other check box at the top of the window, then layers will “snap” to each other when you drag them—that is, when you drag a layer within six pixels of another layer, the layer you are dragging will move automatically so that its boundary touches the boundary of the stationary layer.
