Neu is a simple application that makes it easier to create new documents in the Finder, without you having to open an application first.
It does this by adding "Create Document..." and "Create And Open Document..." menus to various places, including the main menubar, the Dock, and the Services menu that the Finder shows when you right-click on something. You can also trigger Neu from any application using a special key combination.
