This is really simple it a nick changer listed in F key commands. All you do is copy the code paste in Alias then make a .txt file with all the nicks you used, use, or want to use. And add the directory too. Example: (C:\ Programs Files\mIRC\Nicks.txt). I have it listed to F12 key in this key you can change it to the key you want including Shift + F key. You would change to SF. Or Control + F key...
