I have every button mapped to something for my X52, I even use the slider for pageup/dwn for GVs.
While the "i" button looks like it should be programmable, it isn't.
PM me and I'll send you my profile.
I like the way I prgrammed the views/up views all on One HAt using the shift (pinky trigger) key.
If you need help with something perhaps I can help. I've gotten pretty decent with this thing.
