what is the FN key referred to in the drop down list for remapping? (not f-1 etc.)

Help. I have successfully used the system for swapping one key, but in the list, I cannot specifically find the FN key by my arrow keys, which I want to swap. Can anyone shed some light on this? Thank you. Really pleased with SharpKeys, great.
