Fn key on apple wireless keyboard

Hello AHK community, I was wondering if you could help me get the fn key to work.
Using https://ahknet.autoh.../Veil/fnkey.htm FnMapper.ahk to be exact, I've got both fn and eject keys recognized and working.
The problem is that I want to:
swap fn with ctrl
swap eject with del (since I use shift+del a lot)
get the media keys (F's) to work

I was trying to change this code (full version at the bottom, credits it the code) from winamp to wmplayer_app (or something like that) but then I tried F7::Media_Prev for the sake of seeing if it works, so it did, and now I want to make the hotkey fn+f7..9 to work as Media_Prev, Media_Play_Pause, Media_Next. from http://goo.gl/LcY64

hotkeyF7() {
	global fnPressed
	if(fnPressed = 1) {
		IfWinNotExist ahk_class Winamp v1.x
  	Return
		ControlSend, ahk_parent, z  ; Previous
	} else {
		Send {F7}
	}
}
Return

CAN ANYONE PLEASE HELP? I'm so frustrated..

(had to download some missing dll's without which the volume hotkeys didn't work)
