Navigate through the various dialogs

Expand the tree view by a.) double clicking on the shade name, or b.) clicking the plus(+) symbol next to the shade name. Click on each of the dialogs to get an idea of what each looks like. With the "Dialog View" button/tab selected on the top of the pane on the right side, move the mouse over each of the images. Did you notice a border around each of the images when the mouse passed over? Good. Moving right along...
