How do I check how many zombies i've killed?

[buzzcut13 0]

I remember having somewhere around 600 when I stopped playing 2 months ago. I picked back up, same exact character, but I can't seem to get the screen up that shows how many zombie kills and deaths you've had. I think it was I that was the command for it. Someone correct me if I'm wrong, or if you just can't check anymore. Thanks

Well, debug monitor is "insert" on my keyboard.

Bind a key to the Custom 20 option. Mine is Insert as well.
