You can identify elements at any depth in a view.

This is important to remember, particularly if AccuDraw is not active. In these cases, when you are using tools such as Move Element or Copy Element, elements are moved to the Active Depth when you snap to the element with a tentative point (either manually, or automatically via AccuSnap), and then accept with a data point. When AccuDraw is active, it always controls the depth of the element in the view, keeping it at the same depth by default.
