A family of Microsoft word processing software products for creating web, email, and print documents.
If you have a fn key it indicates that you are using a laptop or condensed keyboard. Apple has commandeered the F keys on keyboards of that type to perform system operations, such as Brightness, Contrast, Volume, Media control, etc. In that case you need to include the fn key: fn+Option+F1.
The alternative would be to change the Keyboard Preference in System Preferences to have the F keys as Standard Function Keys.
