Microsoft Sculpt mobile keyboard reverse Fn keys

The hardwiring of the Windows 8 Keys as the default keys instead of the more often used Function Keys drove me nuts. I have far more use for the F1 to F12 keys than the Windows 8 Keys, particularly in Mac OS X.

This is a hardwired feature of the Microsoft Sculpt Mobile Keyboard.

The only solution which works is to sacrifice the Windows 8 keys by permanently setting the Fn in the down position.

I did this by popping off the Fn Key and taping the switch in the down position. I used double-stick permanent mounting tape for adhesion which was then covered by black gaffers tape.

I love that my Function Keys now work as I want them to.

Sure, I no longer have keyboard support for volume - compared to the Microsoft Bluetooth Mobile Keyboard 6000. But I do gain a hardwired Home and End Keys. And I can easily create a macro to control the volume.

Since the Sculpt Keyboard is also half the price of the Keyboard 6000, this hardware modification saves me $20 every time I wear out the keyboard.

I wouldn't worry about battery life from keeping the Fn key pressed down since usually I turn off the keyboard when not used - when the keyboard is used as a mobile keyboard. When used as a desktop keyboard, we will have to see if battery life is reduced.

As per @AkA Kin and @Yuji it seems that AutoHotKey is the solution. Found this great script by tehshane that "remaps the F1-F12 function keys on the Microsoft Sculpt Mobile keyboard to be pressed without having to use the Fn key": https://gist.github.com/tehshane/8765405
