The Select Next Layer command selects the layer just underneath the active layer in the layer stack. The command highlights the layer in the Layers Dialog and makes it the new active layer. If the active layer is already at the bottom of the stack, this menu entry is insensitive and grayed out.

	Note that on a standard Windows-style English keyboard, the default shortcut Page_Down does not refer to the key on the numeric keypad, but to the other Page_Down key in the group of six keys to the left of the numeric keypad.
