This dialog is used to control the "behavior" of the selected relay fork.  Choose one of the three fork "types".

Please refer to Condes relay support for details on the fork "types".

Leg forks

When "Leg fork" is chosen, a leg diagram is shown at the bottom of the dialog window.  You can move legs between the branches by dragging the leg number with the mouse. 

In the example below, leg 1 and leg 3 run branch A, and leg 2 runs branch B.  This would be a way to let leg 2 run a longer loop than leg 1 and 3.
