+Mapping Configuration
+---------------------

+**input** <identifier> map_to_output <identifier>::
+        Maps inputs from this device to the specified output. Only meaningful if the

+**input** <identifier> map_to_region <WxH\@X,Y>::
+        Maps inputs from this device to the specified region of the global output
+        layout. Only meaningful if the device is a pointer, touch, or drawing tablet
+        device.
+
+**input** <identifier> map_region <WxH\@X,Y>::
+        Ignores inputs from this device that do not occur within the specified region.
+        Can be in millimeters (e.g. 10mmx20mm\@10mm,20mm) or in terms of 0..1 (e.g.
+        0.5x0.5\@0,0). Not all devices support millimeters. Only meaningful if the
+        device is not a keyboard an provides events in absolute terms (such as a
+        drawing tablet or touch screen - most pointers provide events relative to the
+        previous frame).
