the 'shading' menu is specific to a panel, so you'll find it at the top of each view panel (not at the top of the window itself, but below the shelf at the top of your view pane)
alternatively, you can hit the 4, 5, 6, and 7 keys on your keyboard to toggle between wireframe, shaded, textured, and lighted modes
that's a "Ch" pronounced as a "K"
