Restore / Show Outliner again When I start Blender, I am shown the Outliner on the right side:



Somehow I very often manage to hide it. I think it happens when I unwrap and have the "UV Edit" window shown on the left side of Blender.

Can anybody tell me how to restore / show it again?

Thank you.
The shortcut for the outliner window is ShiftF9.
