Helllllp!

I've just finished the the 6 part video tutorial on rigging a character and it doesn't mention how to add controls in the channel box for things like foot roll and attributes for the hands such as fist or individual finger closing and opening controls. Hope that makes sense!

Does anyone know where I can find info on how to do this? I've tried analising the walk cycle tutorial kid to find something and looked through Maya's help but can't find anything!

All the best
