I come from windows and now use a Mac (iOS dev). I was so used to all windows shortcuts (shift+ctrl+keyright to select a word, ctrl+c to copy, etc), I know what you mean! I use KeyRemap4MacBook, which kicks in as soon as I connect my hardware windows keyboard to it (which is basically always when I sit down to code). It has a lot of default windows compatibility settings, but you can customize at will. I added a few myself by hand as well (also to get desktop switching the same as I was used to from Ubuntu :).
