Insert corner: In this mode, the mouse is used to insert a user-defined corner on a line.

You can drag a new line from an output pin to an empty space. In this case, the editor automatically finishes the line with a user-defined corner, so that you can continue drawing the connection to the desired pin and force the routing while you are drawing the line.

Corners can then be selected and moved to change the routing of existing lines.
