Ensure that readers see your essential links.
Styles used on the Web suggest that readers love navigation bars, such as the one shown in Figure 5-14.
Creating a PDF navigation bar in Acrobat and then duplicating it across several (or all) document pages is easy. Links can open external web pages or internal PDF pages. Add graphics and other styling elements to make it stand out. Disable printing to prevent it from cluttering printed pages. All of this is possible with PDF form buttons.
Create and manage buttons using the appropriate Acrobat tool. In Acrobat 6, activate the Button Tool (Tools Advanced Editing Forms Button Tool), then click and drag out a rectangle. Release the mouse and the Button Properties dialog opens. Select the Actions tab and click the Select Action drop-down box. Choose Go to a Page in this Document or Open a Web Link and click Add . . . . Another dialog opens where you can enter destination details. Click OK and the action should be added to the button's Mouse Up event. Click Close and your button should be functional. Test it by selecting the Hand Tool and clicking the button.

Or, select World Wide Web Link if you want the button to open a web page. Click Set Action and then OK, and your button should be functional. Test it by selecting the Hand Tool and clicking the button.
By default, buttons are plain, gray rectangles. Change a button's background and border using the Appearance tab in its properties dialog; you can even make a button transparent. Change a button's text label using the Options tab.
The Options tab also enables you to select a graphical icon. Change the Layout: to include an Icon and then click Choose Icon. You can use a bitmap, a PostScript drawing (Acrobat 6), or even a PDF page as a button icon.
Consider creating a no-op graphical button as a background to your other (transparent) buttons. This can be easier than trying to split a single navigation bar graphic into several pieces. Just make sure the active buttons end up on top of the graphic layer; otherwise, they won't work. Do this by creating the graphic layer before creating any of the active buttons, or by giving the graphic layer a lower position in the tabbing order.
To prevent a button from printing, open its properties and select the General tab (Acrobat 6) or the Appearance tab (Acrobat 5). Change Form Field: to Visible but Doesn't Print.
Activate the Button Tool (Acrobat 6) or the Form Tool (Acrobat 5), hold down the Shift key, and select each button until all of them are selected. Right-click the selection and choose Duplicate . . . . Enter the desired page range and click OK. Your navigation bar now should exist on those pages, too. Page through your document to ensure they are positioned properly.
