This video provides very useful Rhino tip: The One Rhino Setting I Always Change for Faster Modeling - YouTube
The tip is configuring middle mouse button to very simple macro: '_Zoom _Selected (or !_Zoom _Selected) in Options>Mouse command.
Neither the tipster nor the Rhino documentation explain well what the Zoom>Selected does. In fact, it ‘kills two birds with one stone.’ The Zoom>Selected fills the viewport with the selected objects, and it changes the view target to the center of the bounding box holding these objects. In other words, the Target option is secretly embedded in the Selected option. The automatic change of the target is extremely useful in the Perspective viewport.
