Från FAQ:
When I use the arrow keys to move when I'm in a game, I press SHIFT to walk, and then try to move right at the same time, but it doesn't work. I just go straight. But it works when I go left, just not right. Why?
Long story short. It desn't work. It will never work. We know it sucks, but, it doesn't work.
For the long version . . . it relates to how the keyboard was designed. Although most people do not realize this, or give it much thought, on ANY keyboard, you can't actually press every key at the same time, and have the computer regonize every keypress. This is due to what's called the "keyboard matrix". Certain keys "share" the same interface to the computer. Because this is being marketed as a "gaming" keyboard, and the vast majority of gamers use the WASD configuration for moving, it's theorized that Logitech created their matrix with this in mind, so that none of those keys would conflict with each other, and very possibly, the G keys as well. Because of that, some concessions were made, and, it appears that SHIFT and UP is being sent on all the lines that the RIGHT key would also use, and thereforce it's not being recognized by your PC. Because this is actually how the keyboard was physically designed, no driver or firmware update will fix this issue. If you normally use the arrow keys for gaming instead of the WASD style, this keyboard probably isn't for you.
