To switch ctrl and fn on your computer, the first step is to switch the two keys on your OS. For Mac OS X, you can use KeyRemap4MacBook. Download the the software and install it. When installation is finished, you need to restart the computer to be able to use KeyRemap4MacBook. After reboot, you will notice a new empty icon which look like a key in your menu bar.

You can open KeyRemap4MacBook from this icon or find the dedicated Preference Pane under « System Preferences ». On the « Change Key » tab, look at « Change Control_L Key (Left Control) » and select « Control_L to Fn ».

After that your need to change fn behavior too. So look at « Change Control_L Key (Left Control) » and select « Control_L to Fn ».

Eventually you can remove the menu bar icon under the « MenuBar » tab. Just unselect the « Show icon in menu bar » option.
