[Request] Key changer

I have some of my skills set on f10, f9, f8, f7

So since its such a pain setting them to f1 etc everyday when i pvp, can some1 make me a simple macro that changes:

f10 : 1
f9 : 2
f8 : 3
f7 : 4

There are some free programs out there that do this for you. Google it you should be able to find some , if not i could make one for you when i get some free time.
