Is your feature request related to a problem? Please describe.
When I scan larger scenes (e.g. rooms) the 3D Viewer get always unusable (e.g. pan movements get very tiny) or stuck at a certain zoom level (perhaps it is also correlated to the distance from the absolute zero point. ). It is really hard to navigate through the scene.

Describe the solution you'd like
Key controls for the 3D viewer. For example WASD for pan control. Ideally independent from zoom level and coupled to the view (for example pan step size could be a fixed ration of the gizmo diameter)

Describe alternatives you've considered
No idea.

Additional context
Different feature but connected to the 3D Viewer: Sometimes switching the view to orthographic would be nice to have.
