Looking for an addon that places the axis of the manipulator in line with...

line segments, so the vertice can be moved in the same direction of any of the line segments. Or is this function already in blender? In some cases these line segments don’t line up with the 3 axis. None of the options at the bottom of the 3d view will line the axis up to these line segments…eg. local,global,normal,gimbel,view. Thanks

Select vertex, hit g, then g again.

Obsurveyor, thank you. It worked perfectly.
