Only one layer of a layered pane is visible. To view other layered panes:
Select the visible pane of the layered panes in the interface or in the Module Browser.
Selecting a layered pane in the Browser does not pop the selected pane to the top of the stack of panes in the interface.
Choose NextLayer from the View menu of the primary window or from the interface pop-up menu (displayed by pressing mouse button 3).
The layer immediately beneath the current pane will be displayed. Repeat this step to view other layers.
