Script to cycle through action sets.

Is there a way to cycle through Actions sets?

Imagine multiple action sets - each action set's first action [is one that is bound to the F2 key and] points to a script that says "go to the next action set, if there aren't any more - go to the first action set". This would allow for someone to open-endedly load as many action sets as they like, and never have to interface with switching them beyond using the F2 key. That would ROCK. You could also craft your sets' key bindings to only be only F3-F12 -- with no combinations of shift or control. That would be a much faster workflow. The only problem I could see arising is knowing for certain which action set your currently in. Also, you would probably want another sript that pushes the set selection in the other direction...
