How to map media buttons on Logitech K260?

Hi everyone, so I've got a Logitech K260 wireless keyboard, and it has some media buttons on it (including a calculator, internet and email shortcut). So far, out of the box, the volume buttons, the play button and the power button work fine. All other media keys don't work, and I'm not really sure how to map them to commands. Also, I'd like to add that next track is labeled as the alternative to "End" and the previous track is "home" (i.e. you'd expect to press shift+end and get to the next track), but this doesn't work either.

I've tried installing the Logitech Control Center, but no luck. Any ideas?
