Groove Agent question/midi grid

When I am using the Groove Agent, I can see the Midi information for only one pad. How do you change from one pad to another?
Or to rephrase this -how do you view the different drums on the midi grid with the groove agent?

I am running Cubase 6 on my MAC 10.6.4

Have a look hereā€¦
Both are deceptively powerful tools!
