Insights can be accessed by right-clicking a word or phrase, through the Review tab on the ribbon, or through the “Tell Me” box.

The information is collected from a variety of sources such as Bing Snapshot, Wikipedia, Bing Image Search and Oxford Dictionary, so you can do everything from a quick lookup to a detailed exploration without leaving the Office app. This feature is also called “Insights from Bing” and helps you learn more about your content by collecting and viewing exactly the right information in the context of what you’re reading or writing. “Smart Lookup” is already available in Word and Outlook and has now been added to Excel and PowerPoint. The ribbon tab text is no longer in all caps and hover states have been added to the ribbon tabs.

For those of you who really don’t like the light theme or just can’t use it, Office 2016 introduces dark design improvements that make it easier to use the interface, including better readability in the Word navigation pane and several Outlook readability fixes (white text on a light background, dark text on a dark background, and disabled text is unreadable). The light theme that has been available in Office may be unusable for some users.
