You can move around inside the window and also zoom in and out (we will cover this in more detail shortly).
You will use this window a lot while creating mods. You can see that the left-hand tree has all of the categories of objects and the right-hand panel has the objects that are stored in a category. The Object Window is where all the objects that you can add to mods are stored.The majority of these buttons are not needed for a beginner, so we will largely leave these alone at the moment. The first is the Creation Kit itself, which has the menus and a number of buttons.
As you can see, it is made up of a number of separate windows called views.
