You got me on lack of precision - you don't need to be touch typing for physical FN keys to be useful.
I realise that whilst just about everything else I do on the keyboard is proper touch (based from F-J), I have to move my whole hands to use the FN keys. I will nevertheless hit F5, F9 etc for compiling / break points / step debugging without looking down at the keyboard.
