While correct, for the keyboard I linked, when you press F13 through F24 it sends Shift+F1 through Shift+F12. Which is not impossible to remap, but what if you need to press Shift+F1?

Hey, this is one of the reasons I bought this keyboard!

For a couple extra bucks you can get them to make each individual key a separate key code by asking them to convert it to Single Usage Code Firmware, which is so nifty to me!
