Navigate the 3D View Using the Ribbon
Navigate by means of panning, rotating and zooming the 3D view using the ribbon.
All 3D view interactions are available on the ribbon. It is not practical for advanced users to use the ribbon for 3D interactions, but the ribbon provides a list of all the interactions. Hovering over a ribbon button will show the tooltip that also shows the keyboard shortcut for that action (if a shortcut exists for that action).
