You can read documents by double-clicking the document from the View pane or by using the Preview pane. To read documents with the Preview pane, drag the heavy gray line located at the bottom of the View pane until you have a 3-panel view, as shown in Figure 18.3. You also can open the Preview pane by choosing View, Document Preview from the menu. Refer to Lesson 6, "Managing Incoming Mail," for information on Preview pane options.
