Intuos4 Touch Ring Cycle Layers, Rotate Canvas

[Ratso5]

Hi there Helpfuls!

I just got an Intuos4 medium to use with Illustrator CS4.
On the Touch Ring, the Zoom and the Brush Size works fine.
But the other 2 standard functions - Cycle Layers & Rotate Canvas, do not work.
The manual specifies these functions are for Photoshop (as is Brush Size).
I thought I could just set the settings for the same thing particular to Illustrator but it doesn't seem to have such functions.

Of course I can simply use these 2 settings spaces for some other function but they sound like they could be pretty useful so I wonder has anyone had any experience with this?

Thanks in advance
Helen
