For on–screen viewing, use hyperlinks in your TOC rather than page numbers.
Sometimes you'll create a document for printing, and other times it'll be read on the computer screen. As you saw in the first lesson's practice session, although the TOC entries are links, you might want them to appear as hyperlinks (as shown in the picture) to make it easier for your readers, especially if it will be read on-screen.
All you have to do is change the way your document is viewed to Web layout view. On the View menu, click Web Layout. To see the page numbers instead of hyperlinks, switch back to print layout view.
If you know that a document will not be viewed on-screen, you can choose to disable hyperlinks in the Index and Tables dialog box by clearing the Use hyperlinks instead of page numbers check box.
Note See the Quick Reference Card for details on how to create a TOC in a separate frame for a Web page.
