About This Online Manual

# About This Document

This online document is intended to be read through any Web browser that supports frames, Javascript, and cascading style sheets. If your browser cannot display the Javascript-based table of contents, it should display a plain HTML version of this document automatically. You can also display the plain HTML version through the menu in the left-hand frame, or by clicking the button below:

To redisplay the Javascript-enabled version, click your browser's Back button or click the "Javascript Version" text link in the manual's table of contents or index.

| Tip: Add the plain HTML version of the manual to your bookmarks or favorites if you want to refer to it instead of the Javascript version.

## Browser Compatibility

For best results, use the latest version of Netscape Navigator or Microsoft Internet Explorer.

## Table of Contents and Index

This document's table of contents and index (if present) use an expandable Javascript tree. The links at the top of the tree let you expand or collapse the entire tree:

1|2|3|All | Click these links in the TOC or index to expand or collapse the tree to its first, second, or third level. The "All" link expands the tree to show all nodes. For large manuals, expanding or collapsing the tree fully may take several seconds.

Each node in the tree has an icon:

| A "plus" icon indicates that the node has subsections that you can display by clicking the icon.
| A "minus" icon indicates that the node's subsections are displayed. You can hide the nodes by clicking this icon.
| A box icon indicates that the node has no subsections.
| An arrow indicates the current position in the table of contents (Netscape Navigator 4 only).

The table of contents and index include a menu that allows you to display various pages in this document. Some menu options may also take you to external Web sites.

## Document Pages

Each page in the main flow of this document has arrows at the top and bottom that let you move through the document without using the table of contents:

| The previous chapter or appendix displays when you click the left arrow icon.
| The next chapter or appendix displays when you click the right arrow icon.
