Tweak

Modify > Translate > Tweak - The Tweak tool allows you to interactively translate the points, edges and polygons that make up your object. You don’t need to be in a specific mode to use it. Points, Edges and Polygons can all be tweaked no matter which mode you are in. Clicking with the left mouse button will drag the elements, clicking with the right mouse button will extend new edges or polygons.
