Guys, I see some misunderstanding in the 13. Views » Project 2/2 video and the following Quiz, as below:
Selecting Edit -> Frame Selected (or hitting F or double-clicking a GameObject in the Hierarchy) does in fact center the view onto the selected GameObject. In contrary, doing what you are telling (Shift-F, or Edit -> Lock View to Selected which is the same), locks the view to selected GameObject. The latter is seemingly the same as first but, in addition, it will keep framing the object as it moves, thus making it possible to continuously track a mobile object (e.g. if you like to track it in run-time or simply while moving it around using the transform tool in the scene). Try it
Edit: The same goes for 14. Views » Scene video.
Also, remember it won’t work from anywhere. Hitting F only works when your cursor is over the scene view, while shift + F works from everywhere.
