"Tell me" offers suggestions rather than asking you to be specific
Microsoft is making a move to aid users when it comes to finding important features and options they may want to use when it comes to the Word Web App. A brand new "Tell Me" feature has been implemented that aims to act as a kind of virtual assistant for those needing a little extra help when it comes to Word.
Tell Me, via PC World, allows you to search for ideas and concepts for what you want to do, so even if you're not sure exactly what it is you're trying to accomplish, there's a way to find it. You can give Tell Me a vague idea of what you want to do, like "enlarge text" and it'll offer you sufficient options with which you can do this. It's handy, especially for users with a little less experience navigating the tools and options of Word.
This feature is nowhere near as garish and annoying as the paper clip that haunted our collective dreams back in the day, and it looks to be pretty useful. Have you given it a try yet?
