You can browse help topics using the Help window or Help view. Which one you use is simply a matter of preference; the view is well integrated with the workbench and is good for quick help lookups. The Help window, on the other hand, has more real estate and may be preferable for longer reading.
The Help window is a window separate from the workbench used exclusively for browsing, searching, and printing help. To open the window, select Help > Help Contents from the menu. This opens the help window with the Contents view visible, which shows the table of contents.
To navigate the Help window:
Go Back and 
Go Forward buttons to navigate back and
forth. These behave the same way as in Web browsers.
Home button to return to the help home page as shown above.
The two main frames of the Help window can be maximized to take up the
entire window. To maximize a frame, click the 
Maximize
button in the toolbar, or double click on the view's title header. To return the
view to its original size, click the 
Restore button or double click the title
header again.
To print a topic from the Help window:
Print button in the Help toolbar.The Help view provides the same features as the Help window, but in the same window as the workbench instead of a separate one.
While reading a topic, you can find out where the topic is located in the table
of contents by clicking the 
Show in table of
contents button in the toolbar. This will display the table of
contents with the topic highlighted.
