Just bought a KUL ES-87 Tenkeyless Keyboard for my Mac. Aside from the blue LEDs (why blue? why?), I've really digging the weight and key feel and sound. And as a great bonus F7-F12 keys are controlling volume and media playback just like the stock keyboard.
BUT, there is also this row of keys that do nothing on a Mac.

To me, these are wasted keys — is there any way I can reclaim them to do something useful?
