Help in Office 2013 is only a click away, no matter which app you are using or what you might be doing with it. You can find the Help tool, which resembles a question mark, in the upper-right corner of your application window. When you click it, Office displays a Help window you can use to search for specific assitance, click a popular help category, or browse through articles and training options related to the main features and functions in your app.
In your current Office 2013 app, in the upper-right corner of the screen, click Help.
Click to enter a word or phrase for which you want to search.
