Help Viewer

Help Viewer is an application used to show you help screens, which are written in HTML.
Help Viewer is centralized and is stored in System > Library > CoreServices.
When your Mac is connected to the Internet, help Viewer automatically displays the latest information available.
More than one Help Viewer window can be opened at a time.
The Home button is actually a centralized repository of all help files on your system. You can jump between one online manual and another simply by clicking and holding the Home button and choosing a new application.
