Microsoft added “Insights” to Word Online, new feature which will help users search the web right from Office Online.
To get Insights, right-click on a word (or phrase) you want and select Insights from options. Office Online understands what you are looking for and then uses the power of Bing to bring in relevant information from a variety of sources like Bing Snapshot, Wikipedia, Bing Image Search, Oxford English Dictionary and the web.
This simple feature is very useful and suppose to help users find more information, explore interesting articles that are related to the information they are looking for working on their documents.
