Ingame support screenshot
Press “Print Screen.”
Doesn’t matter where you are (it’s part of Windows…) it copies your screen output to the clipboard. You can then paste it into Paint or whatever image editor floats your boat.
GW2 also catches the key, and saves a screenshot. Look in the chat box, it will tell you where and what it saved it as.
That wasn’t my point. I’m aware of “Print Screen”. The print screen button in game takes the shot and adds it to the support ticket in game. “Print Screen” won’t do that. Hence they need to make a shortcut key for it.
