Question about spell slots

There were questions about my map "Legends Od Thaeron: The Great Revenge - Chapter I: Burning Cold". You're asking how to change positions of spells? Well, this question has been discussed many times on this forum, but...
Here's what I did:
With any mpq-extracting tool you export a file named *AbilityFunc.txt (* - the name of the race. Example: NightElfAbilityFunc.txt), then open it with your notepad :) and change the coordinates in "Buttonpos" line for a spell u want. (The numbers go not from 1 but from 0, so if u want a spell to be in the upper left slot u should set coordinates to 0,0; lower right slot - 3,2; etc.).
Then put that modified txt in your war3patch.mpq (or other mpq, but you'll need to do some work to make warcraft3 see that mpq. You can use wc3campaigns's Custom Campaign Installer, or write a bat-file as I did, or maybe you know some other way).
And that's all. As you can see, no coding (like some people thought).
