You might find, while using a Windows application such as Microsoft Word for Windows or Microsoft Excel, that you want to use Viewer to search for a text string displayed in that application. For example, if you're working on an article using Word for Windows, you might want to select a name in that article and then use Viewer to search an encyclopedia or dictionary for that name.
An application called QuicKeys is provided with Viewer to give you this capability. QuicKeys allows you to specify a unique combination of keystrokes for each book you want to search. When you press those keys, Viewer searches the book for the text you selected in the application. You can search using either index keywords or Viewer's full-text search capabilities.
