Defining Hyperlinks

A hyperlink is an area of a page that can be clicked to send the reader to a new page, open a new document, move to a Web page, or send an e-mail message. There are two parts to creating a hyperlink. The source is the object or text that you click to trigger the hyperlink. The destination is the page or Web link you go to.

TIP

You must define a destination first, before you define the source.

TIP

Hyperlinks are applied when the file is exported as an Adobe PDF (see page 493) or when you use the Package for GoLive feature (see page 517.)

To choose the type of hyperlink:

1.	Choose Window > Interactive > Hyperlinks. This opens the Hyperlinks palette . The Hyperlinks palette is used to define both the destinations and the hyperlinks.
2.	Choose New Hyperlink Destination from the Hyperlinks palette menu. This opens the New Hyperlink Destination dialog box . The New Hyperlink Destination dialog box lets you set a page destination.
3.	Choose the type of hyperlink from the Type menu as follows : The Type menu lets you choose the type of hyperlink destination. Page creates a page destination that links to a specific page in the document. This is the only type of hyperlink that lets you set a magnification for the link. (See the next exercise for how to create a page destination.) Text Anchor creates a link to a selected area of text. This option is only available if you have selected text. (See the exercise on page 427 for how to create a text anchor destination.) URL lets you link to an Internet page. (See the exercise on page 427 for how to create a URL destination.)

A page destination specifies the page and the magnification to use when you move to the link.

Fit View displays the visible portion of the page. Fit in Window displays the entire page in the document window. Fit Width or Fit Height displays the width or height of the page. Fit Visible displays the areas that contain text or graphics. Inherit Zoom displays the same magnification that was active when the link was clicked.
6.	Click OK to create the destination.

TIP

Don't worry that you don't see your destination listed in the Hyperlinks palette. Destinations aren't shown there. Destinations are shown when you define the hyperlink source.

Tips for Hyperlinks

Hyperlinks don't have to be ordinary text or plain frames. You can use placed images, text inside tables, or even inline graphics as the source object for hyperlinks.

If you use text as the source object for a hyperlink, you may not want to display the clunky rectangle as the link indicator. Instead, consider using an underline with colored text (applied as a character style), to indicate where the hyperlink is located. This changes the link so it is more similar to links in Web pages.

Finally, you can automate some of the process of creating hyperlinks by applying the source object to a master page. The hyperlink can then be visible on all the pages based on that master page.

As you work, you can edit the settings for the hyperlink source.

To edit hyperlinks:

1.	Double-click the hyperlink entry in the Hyperlinks palette. or Choose Hyperlink Options in the Hyperlinks palette menu. This opens the Hyperlink Options dialog box . The Hyperlink Options dialog box lets you edit the settings for hyperlinks.
2.	Make changes in the Hyperlink Options dialog box.

Once you have created a hyperlink, you can change or reset the text selection or frame that was used as the source object.

To reset the hyperlink source:

1.	Highlight the text or select the frame that you want to be the new hyperlink source.
2.	In the Hyperlinks palette, select the hyperlink that you want to change.
3.	Choose Reset Hyperlink from the Hyperlinks palette menu. The original source object is changed to the new selection.

If you have named an external document as a destination, you may need to update the hyperlink to that external document. For instance, if the page name or location has changed, the hyperlink needs to be updated.

To update the hyperlink to an external document:

1.	Select the Hyperlink in the Hyperlinks palette.
2.	Choose Update Hyperlink from the Hyperlinks menu palette.
3.	Choose Reset Hyperlink from the Hyperlinks palette menu. TIP If the external document is closed, hold the Opt/Alt key to open the document.
