When viewing Help, you can maximize the viewer or resize it to suit your liking. The buttons for changing the window size are located in the upper-right corner.
You can open or close the left-hand tabs, depending on how you like to work. When you close the tabs, the right-hand pane is maximized so you can see as much topic content as the size of the HTML Help viewer allows.
Just like a browser, the HTML Help viewer includes Back and Forward buttons for navigating.
The Options button opens a menu with selections for hiding the left-hand tabs, going back and forward, stopping a topic or Web page from loading, refreshing the information displayed in the window, printing, and turning search highlighting on or off. You can also access Internet options from this menu.
Since the HTML Help viewer uses components of the Internet Explorer browser, it can take you to Web sites on the Internet.
