(located in your iWork '08 or '09 folder)

Pages is a word processing and desktop publishing application. This is what we'll now use to replace AppleWorks.
If Pages is not in your dock, you will find it in your applications folder, inside the iWork '08 folder. iWork '08 includes Pages, Keynote, and Numbers. If you plan on using these applications on a regular basis, you'll want to drag the icon of each application into your dock so they are handier to get to.
Do you use Keynote? If the answer to that is yes, then you're well on your way to understanding Pages. You'll see some of the very same features in both applications: the inspector, media browser, masking, shapes, tables, charts, and lots more. So learning one of these applications will automatically qualify you as an expert in the other application!
