Hey guys

I was wondering if anyone could tell me where I find the file that holds the information for Steams in game monitor. For example when I go to play Counter Strike my steam changes to "In Game Counter Strike" and when I am just on my desktop without any games open it says "Online" etc

I was wondering if some awesome person could tell me what the file is called and where it is in my steam files that monitors all of that so I can edit it.

Thanks,
Luke
