Changing Keys

Hello Community,

Because i like to game sometime son my MBP, i have the question:
Is it possible to change the CTRL and the FN keys somehow?!? Because this suits games much better and makes controls easier!

Are there any programms that change the functions of keys? Now ive looked around a bit and found DoubleCommand, this works fine but i have to configure it again everytime i restart my mac. Is it possible to physically take the key out, changing the CTRL and the Fn as they both have the same size?? If yes are there any instructions in how to change the keys safely on a MBP 13"??

Another problem: If i use bootcamp to install windows, are there any programms to change it aswell on windows??


Thanks for your help!
