Lol 26 views and not one reply looks like there are many little hurt children in here. Its ok I got it guys, not hard really. cant believe the staff to act like this?
I never owned a g15 or a logitech keyboard, for that matter.
Try have a look at this guide (which i've found on Google), i'm going to guess it works by setting up combination of keys to each "G" key, and then binding the set of key to a command - as you would usually do in AA2.
P.s. the staff isn't supposed to have knowledge related to each and every single problem you happen to come across on your hardware.
