That second guy sounds like an idiot, even if he is just making fun. I mean, who's so lazy that they type "n" instead of "and"?
The fun way to find a keylogger is to search "search inside files" and type "askjksladjflqwjerljsdf324jsj03jfaklj" -- if there is a keylogger, it'll find that file because you just typed it.
