To expand some more on what Dave and Ant said about the arrow keys, they allow you to step up or down in the hierarchy, the up key won't necessarily take you to the top most level, just the parent of the current selection for example in this group, each node is a child of the previous. Code: Group1 >node1 >node2 >node3 Selecting node3 and pressing up will select node2 and not the group node, you'll have to press the key two more times. Hope that helps. The Outliner is really handy, I feel naked without it!
