Start by creating a blank page exported to PDF. You can create a document where you may have a number of passwords listed and convert it to PDF. If not, use Microsoft Word or your favorite application to either export to PDF or print to PostScript and distill the PostScript file in Acrobat Distiller.

In this example, I'll use a blank page exported from Adobe Illustrator as PDF.

Open the PDF file and select the TouchUp Text tool from the top level toolbar. Text can be added by creating form fields, but using the TouchUp Text tool will enable you to automatically create URL links for Web sites.

To add a line of text in a PDF document from scratch in Acrobat 5.0, press the Control key (Windows) or Option key (Macintosh) and click the mouse button.

Acrobat 5.0 enables you to create a raw line of text by using a modifier key and the TouchUp Text tool.
