7.17. Raise Layer
The Raise Layer command raises the active layer one position in the layer stack. If the active layer is already at the top or if there is only one layer, this menu entry is disabled. If the active layer is at the bottom of the stack and it does not have an alpha channel, it cannot be raised until you add an alpha channel to it.
7.17.1. Activating the Command
You can access this command from the image menubar through Layer → Stack → Raise Layer,
or by clicking the up-arrow icon at the bottom of the Layers dialog.
