I know I've done this before but I can't find it. After extensive searching of the mostly useless Help file I did find this line: "Level Sets can be created, renamed or deleted through the context menus." however I cannot find the context menu to Create a level set. Perhaps someone can enlighten me?

Additionally, I have a file that has a reference in it and for some reason it will not display the reference in the Layout if I render it as anything other that Wireframe or Default, is there something I am missing?
