So after blindly updating my iBook the latest OS X update ruined my control key life. Searching around frantically I found that there were others reporting the same thing. Ack! Without control where the completely inane CAPS LOCK key is I'm lost. So off to a big Google search it is. Third hit down yielded DoubleCommand. Bang! Back in business and it seems a bit simpler than uControl. (which they have since fixed by the way) In the end I don't think I needed all the functionality that uControl offered. All I wanted to do was swap a couple of keys. Simpler is usually better in my book. Life is good again.
