Back

The Back button takes you to the previous page in the history list. The history list is a reference to pages you have viewed.

Forward

Clicking on the Forward button brings up the next page in the history list. (Available only after using the Back command or a history menu item.)

Home

The Home button links to the home page designated in your preferences.

Open

When clicked, the Open button produces a dialog box that allows you to visit any page whose URL you can supply.

Or you can click here and go back if you get confused.

Take a look through Netscape Handbook, the online manual, for complete details on how to use the toolbar.
