Select all opaque areas of a layer

When working with images that contain transparency, you can quickly select all the areas that are opaque by using the Load Selection tool. In other words, Load Selection creates a selection that goes along the edges of a layer — if a layer is rectangular, a rectangular selection will be created, if it's a circle — it will create a circular selection.

Similarly, when used on a layer mask, Load Selection will automatically select only the areas that are visible, leaving the masked areas outside of the selection.

Do any of the following:

• Choose Edit > Load Selection.

• Choose Tools > Select > Load Selection.

• Press Command ⌘ + Option ⌥ + L on your keyboard.

• Command ⌘ – click a layer thumbnail in the Layers sidebar.
