Connecting two points via straight lines that are only horizontal and vertical, use for first horizontal then vertical

Curved paths using a Bezier curve can be created using the "..controls() ..()" command, with one or two control points.

\draw (0,0) .. controls (1,1) .. (4,0)
      (5,0) .. controls (6,0) and (6,1) .. (5,2);
