How to deactivate User Persp (Local) view? I am accidentally going to User Persp (Local) view, and I don't know how to get back to a normal Perspective view..

When I'm in the User Persp (Local), I can see the objects on the viewport, but when I render it.. I got nothing in the render result



The point is, how to get back to normal perspective view?
To go back to Global perspective view, go to View -> "View Global/Local". The hotkey is Numpad /. You probably pressed this when you accidentally switched to local view. This also works for otho view as well, from global to local and back. (Just to add it in, here's a YouTube video explaining how it can be used to un-clutter your scene for easier editing.)
