appendix A Scene navigation and keyboard shortcuts
Operating Unity is done through mouse and keyboard, but it isn’t obvious to a newcomer how the mouse and keyboard are used in Unity. In particular, the most basic sort of mouse and keyboard input is navigating around the scene and looking around the 3D objects. Unity also has a number of keyboard commands for commonly used operations.
I’ll explain the input controls here, but there are also a couple of web pages you could refer to (these are the relevant pages in Unity’s online manual): http://docs.unity3d.com/Documentation/Manual/SceneViewNavigation.html and http://docs.unity3d.com/Documentation/Manual/UnityHotkeys.html.
A.1 Scene navigation using the mouse
Scene navigation is primarily done with three main navigation maneuvers: Move, Orbit, and Zoom. The three movements involve clicking and dragging while holding down a combination of Alt (or Option on the Mac) and Control. The exact controls vary for one-, two-, and three-button mice; table A.1 lists all the controls.
