Swap the Fn and Ctrl keys on a Lenovo ThinkPad

Lenovo decided to have the Fn and Ctrl keys as the first and second key respectively on the lower row of the keyboard on their ThinkPad laptops. Being used to having them in the opposite order on my Dell laptops, this has been the source for quite a lot of annoyance with my new work laptop.

But I just found out that there's a BIOS option for swapping the Fn and Ctrl keys on a ThinkPad. Yay!
