You can print all Segment Editor effect parameter names by typing this into the Python console:

```
print(slicer.mrmlScene.GetFirstNodeByClass("vtkMRMLSegmentEditorNode"))

```

You should get something like this:

```auto
vtkMRMLSegmentEditorNode (000001867E52D360)
  ID: vtkMRMLSegmentEditorNodeSegmentEditor
  ClassName: vtkMRMLSegmentEditorNode
  Name: SegmentEditor

  ActiveEffectName: 
  MaskMode: PaintAllowedEverywhere
  MaskSegmentID: 
  OverwriteMode: OverwriteAllSegments
  MasterVolumeIntensityMask: false
  MasterVolumeIntensityMaskRange: 0 0

```

You can find valid parameter values by looking at the source code of the effects (e.g., search for the parameter name in entire Slicer core or SegmentEditorExtraEffects extension source code).
