   MANUAL_PROBE command above for details on the additional commands
   available while this tool is active.
-- `BED_MESH_OUTPUT`: This command outputs the current probed z values
-  and current mesh values to the terminal.
-- `BED_MESH_MAP`: This command probes the bed in a similar fashion
-  to BED_MESH_CALIBRATE, however no mesh is generated.  Instead,
-  the probed z values are serialized to json and output to the
-  terminal.  This allows octoprint plugins to easily capture the
-  data and generate maps approximating the bed's surface.  Note
-  that although no mesh is generated, any currently stored mesh
-  will be cleared.
+- `BED_MESH_OUTPUT PGP=[<0:1>]`: This command outputs the current probed
+  z values and current mesh values to the terminal.  If PGP=1 is specified
+  the x,y coordinates generated by bed_mesh, along with their associated
+  indices, will be output to the terminal.
+- `BED_MESH_MAP`: Like to BED_MESH_OUTPUT, this command prints the current
+  state of the mesh to the terminal.  Instead of printing the values in a
+  human readable format, the state is serialized in json format. This allows
+  octoprint plugins to easily capture the data and generate height maps
+  approximating the bed's surface.
 - `BED_MESH_CLEAR`: This command clears the mesh and removes all
   z adjustment.  It is recommended to put this in your end-gcode.
