control 和commond 替换，保持windows的习惯。
There's an easier way as well
Go to System Preferences -> Keyboard -> Keyboard tab -> Modifier keys
Swap the Control and Cmd keys
Select Ok
Now:
Control+C = copy
Control+V = paste, and
Control+Z = undo

脚本方法映射 control键盘

I was able to get this to work by using a combination of DoubleCommand and jtbandes hint from here. First check the function key acts as control key box in Double command. Then save the file ~/Library/KeyBindings/DefaultKeyBinding.dict with the contents
{"^c" = "copy:";}
{"^v" = "paste:";}
{"^x" = "cut:";}
After you logout and log back in you should be able to use fn-c to copy etc. There are obvious drawbacks to this approach. You have to explicitly define every command you want to use fn for and mapping to control and then fn is really hacky. Unfortunately I wasn't able to get it to work another way. At first I thought you might be able to select both the "command key acts as control key" check box and the "fn key acts as control key" but that didn't seem to work. Ditto for changing to control with Alex's method above. I was also unable to find the modifier for assigning commands to fn, and Apple's documentation seems to indicate that it's done at a lower level than keybinding has access to. If someone knows a better way of doing this I would love to see it.
