This is my story every day: "you wanna go left? No you wanna go PageUp!", "You wanna go right? Here's a PageDown for you!" "AAAAAAAARRRRGH"

I have a slightly older model that also moves the PgUp/PgDown keys to the arrow keys. I never really had the problem of pushing them instead of left/right, but I was annoyed at it at first because I couldn't find PgUp/PgDown. After using it for a few months, I actually prefer that layout.
What annoyed me more was the swapping of ctrl/fn from my older model (Fn is at the leftmost now). I got used to that too, though I would still prefer ctrl on the left.
As for the keyboard itself, I preferred the pre-chiclet keyboard on the old thinkpads, but of the current-generation laptops I've tried, it's still the best one by miles.
At least on my 5y old Thinkpad Edge 11 it was easy.
Use something like a credit card to remove the keys. And put them back with a firm press.
