Using the "Build" Menu in Content Areas
Build Content replaces the "Create Item" and "Build" buttons, and presents several new options.
Build Content: You can still choose "Item" under "Create," and it behaves exactly as it did in 9.0 - no changes. But additionally, you have specific tools for adding just a file, or an Image, Audio, or Video File. And a new tool called Mashups lets you embed media from Flickr, SlideShare or YouTube.
