How can I switch the function and control keys on my laptop?

Solution 1:

There's sadly no way to do this in the OS, since the Fn key isn't actually recognized by Windows.

You might actually be able to do it in your BIOS setup screen, but it's unlikely.

Solution 2:

I tested the function key on my laptop (Latitude D830) . It doesn't produce a scan code by itself. I verified using Keytweak http://webpages.charter.net/krumsick/ Which is an excellent tool for remapping keys in most cases.
