I believe what John has described has to do with reversing things like Gobo Rotate.
As far as I know, you can't reverse Effects. (With one exception, see below) And you can obtain symmetrical effects depending on the rig setup.
For instance, with a row of Movers under a truss; Get the desired Effect running, like a Tilt Effect Press and hold FAN and then select Center from the bottom right monitor. While still holding Fan adjust the Effects Offset Encoder.
With movers on either side of the rig; If you apply a Sine Effect to the Pan then you will need to enter a 180 degree offset on one side of the rig. Because it is a Sine wave the result is an apparent "reversing" of the Effect on that side.
