Creating selections from layers
You can create a selection from a layer, multiple layers, or layer group. Selections from layers are based on layer transparency. When a layer contains transparent areas, only the areas with content are selected. You can add the content of a layer, or layer group, to a previous selection. To modify a layer-based selection, you can subtract or intersect the content of a layer, or layer group, with a previous selection. Intersecting includes only those parts that are common to all selected layers.
