Hello ROOTers,

Could anyone tell me how to "zoom" geometries in the GL view? The ROOT users guide says that j/k keys works as zoom in and out. But its behavior is very similar to "Dolly" explained in the text. Because I can "enter" the O rings of $ROOTSYS/tutorials/geom/rootgeom.C by using only "Zoom" and "Truck" (see the attached). I think the zoom functionality should not allow the camera to enter the O ring.
