At home I have a mac and use a wired apple keyboard with it. At work I use a laptop running windows 7. I have found myself pressing the wrong keys when I get home on my mac because on windows the keys on the laptop are so close together, so I thought I'd use a mac keyboard on windows 7. However I have it now hooked up and I want to be able to make the CMD button work as the control button (like in a mac), and I also need to use # key, but alt + 3 doesn't make it work. So basically, how can I map it to be the same basic functionality as a mac?
