Is it possible to configure dolly [www.sidefx.com] so that it isn't bounded by the screen when using Space+RMB? I want Houdini scene view to continue to zoom out as long as I hold down Space+RMB while moving the mouse downwards, even if it hits the edge of the screen.

I know the mouse wheel can achieve something similar, but I'm asking specifically about Space+RMB dolly.

Thanks.
