# Oracle Information Navigator

The Oracle Information Navigator is a Java-based addition to the Oracle Documentation Library that acts as a browseable site map. The expandable tree lists every major book and chapter within the Oracle Documentation Library.

The Navigator "tree" allows you expand, select and view information in the library without having to visit intermediate pages.

### Basic Navigation

Using the Oracle Information Navigator is as simple as expanding a tree item and double-clicking the selected item to see it displayed. The items in the tree are either referred to as "Branches" or "Leafs".

> Branch
>   An item in the tree that contains other items. Examples of Branches are folders and books. When expanded, the icon of the Branch changes to indicate that it is open or expanded.
> Leaf
>   An item in the tree that represents a readable document. Examples of Leafs are chapters of a book, a descriptive page like this help page or a problem report. Double clicking on a Leaf displays the content of that Leaf in the browser window.

### Expanding and Collapsing

Expanding and Collapsing of a Branch can be accomplished in one of three ways.

1. Double-clicking on the label of the Branch.
2. Clicking on the plus/minus indicator to the left of the Branch icon.
3. Selecting the Branch and pressing the return key.

### Search, Home and Help

A toolbar runs across the top of the search window. The toolbar provides single click access to some important operations, including.

> Search
>   Activates the Oracle Informaton Navigator Search utility provided with the Oracle Developer Library (see Basic Searching).
> Home
>   Resets the Browser window to the opening page of the information library. This page is defined to be the "Home" page.
> Help
>   Navigates you to this collection of Help pages.
> Filter Menu
>   Displays a platform or category listing that can be used to filter certain classes of information from the tree of the Oracle Information Navigator (see Filtering).

### Filtering

Some information provided in the library may only apply to a specific platform or category of information.

To help reduce the amount of information, the Oracle Information Navigator can be set to remove anything that does not fit a selected operating system category.

Example - if you only wanted to look at documentation that only applied to the to the Windows 95 or Windows NT operating system, selecting "Windows NT/95" from the Filter Menu would hide all information that was specifically identifed for other operating systems.

To reset the tree to the full content listing, simply select "All" from the Filter Menu.

> ##### NOTE: Not all instances of the Oracle Information Navigator make use of the Filtering features. This is an application configurable option.

> ##### NOTE: Filter selections do not affect searching and search results.
