The Saved Viewpoints window is a dockable window that enables you to jump to preset viewpoints without having to navigate each time to reach an item.
Viewpoint animations are also saved with the viewpoints, as they are simply a list of viewpoints treated as keyframes.
Icons are used to represent different elements:
represents a folder which may contain all other elements (including other folders).
represents a viewpoint saved in orthographic mode.
represents a viewpoint saved in perspective mode.
represents a viewpoint animation clip.
represents a cut inserted into a viewpoint animation clip.
You can select more than one viewpoint by either holding down the CTRL key and left-clicking, or by left-clicking the first item, and then clicking the last item while holding down the SHIFT key.
You can drag viewpoints around the Saved Viewpoints window, but you cannot save any changes.
There are no buttons on this window, and commands are invoked through context menus.
