With "view" you can save views (positions of everything) with specific names.  Then you would save a session to keep them.  Later when you restore the session you can use "view" again (or "fly") to transition gradually between those views.

To translate a specific distance you would use "move" but I personally don't think of it as the position of the camera, but instead the positions of the scene or the models in the scene.  You could either do the "move" during your animation or you could use it to create your saved views as mentioned above.

I hope this helps,
