There are two ways in which you can preview topics — in the Topic Preview pane or in a separate window. By default, topics are displayed in the separate window.
From the Tools menu, select Options.
On the General tab, clear Preview in separate window.
Click OK.
Click the Topics tab.
Select the topic to view.
Click View
. The topic appears in the separate window, which is always
on top of the program window.
Tip: You can leave the window open and make changes to the topic in WYSIWYG. When you click the title bar in the Preview window after you edit the topic, the window updates the content to display the new changes.
