Here's what we do (abridged for clarity :-). We just want pan and zoom,
using button1 and shift-button1, respectively...

         // Disable default interactors
         svgCanvas.setEnableImageZoomInteractor(false);
         svgCanvas.setEnablePanInteractor(false);
         svgCanvas.setEnableResetTransformInteractor(false);
         svgCanvas.setEnableRotateInteractor(false);
         svgCanvas.setEnableZoomInteractor(false);

         // Add my pan and zoom interactors
         svgCanvas.getInteractors().add(new PanInteractor());
         svgCanvas.getInteractors().add(new ZoomInteractor());

=2E..

     class PanInteractor extends AbstractPanInteractor {
         public boolean startInteraction(InputEvent ie) {
             if (!(ie instanceof MouseEvent))
                 return false;
             MouseEvent me =3D (MouseEvent)ie;
             return me.getID() =3D=3D MouseEvent.MOUSE_PRESSED
               && (me.getModifiersEx() & MouseEvent.SHIFT_DOWN_MASK) =3D=3D=
 0
               && me.getButton() =3D=3D MouseEvent.BUTTON1;
         }
     }

Our custom ZoomInteractor is similar.
