You best program your controlls by hand, I think.
That is funny - as far as I remember, one can't change a key setting at once.
I had to click "assign additional key" or how it's called. Now you enter your desired setting.
After that, you may delete the original first one.
You could get a "THRUSTMASTER T. Flight Stick X" with a head button for panning views
for some 30,- Dollar, I suppose.
I used that before TrackIR; I had a thumb button assigned to toggle between snap and slide view.
With the top hat I could now get either 8 fixed view angles, or move my slide view.
I was pretty good at it after a while.
I don't think, TrackIR would give you migranes, as it is just like glide view - only that your head moves
controll it instead of a hat switch. Nothing gets close to it, once you familiarised yourself with it.
It's a bit expensive to buy, only to find, it DOES give you headaches, but when you know someone you
could borrow it from - might be worth a try?
