New keyboard with programable keys

[sinus]

Hi all
Today I change to a new keyboard, Corsair K55 RGB.

I have spotted, that this keyboard has 6 keys to program. Means, I can store some keys for each of these.
Now I have to think, what makes sense, specially for IMatch.
I know, that there are some soft out there, where we have tons of programable possibilities.
But I like more simply to press a key (G1-G6).

To be honest, I did not miss such keys, but since I have now six, I guess, I will use them.

If you have a tip, what single keystrokes I could add on a such a key, please let it know me.
