In addition to anything you may find on the AU website, you may find the resources listed in this blog article

of some use. In particular, the course materials from the two AUGI Training Program courses I taught some time back should give you a good grounding in the basics of the Schedule Feature. You do have to be a member of AUGI to access those, but membership is free. Those materials were prepared prior to the ribbon (and prior to the last update of the schedule feature in 2007, when a handful of additional automatic properties were added), but the basics of the schedule feature have not changed substantially since then.
