+![DQz11N1G-DE Layout Image](https://u.cubeupload.com/ddklg/OPBN5q.jpg)
+
+# Default Layout for DQz11N1G-DE
+
+This is the layout corresponding to what the Maltron keyboard DQz11N1G-DE I
+own came with (using the original pre-installed controller).  Note that this
+differs from German Maltron layout as published on [Maltron's
+website](https://www.maltron.com/germany.html).  Use the photo above as a
+reference for the layout implemented here.
+
+I did not find any official documentation about the the Function Lock key on
+the original Maltron keyboards.  It seems that it implements some of the
+features that are documented for the one-handed Maltron keyboards.  Most
+keys don't send any keycodes at all when function lock is enabed.
+
+We instead map some of the Quantum keycodes (mouse keys and audio control)
+in the middle (keypad) section of the keypad, when Function Lock is enabled.
