+	Toggle bewteen layers 'always-on-bottom' and 'normal'. When a window is
+	in the 'always-on-bottom' layer, it is rendered below all other
+	top-level windows. It is anticipated that this action will be useful

 *<action name="ToggleKeybinds">*
 	Stop handling keybinds other than ToggleKeybinds itself.
 	This can be used to allow A-Tab and similar keybinds to be delivered
