SYRAM

I was wondering if anyone knows a keyboards strokes recorder which I am able to inject into a process so that it plays back what I've recorded while the window is minimized (background). For example: i want this to auto-farm in a game where i need to kill the monsters in the desert and collect the loot so i do not have to waste a fully working computer on it all day. I am using JitBit Macro Recorder, it does everything well, except it only runs foreground. Let me know guys, have a nice day!
