Unknown keyboard key!?

Hello dear Users, I have a stupid question - I have a Cherry G-224 keyboard, like in that image from amazon.de



it's the key between the left ctrl/strg key and between the left/Windows key, the symbold of that a key is a small 'k' and a curious fat small "i" - looks like a candle. How can I use that key? Especially I like to use more and more autohotkey.

Hi Zero,
Isn't it a function key which works with the special symbols under your Fx keys ? (e.g. function+F5 to F8 would control the media player i guess).
rgds,
