Zqscefbthmukoawxdrvgynjilp 

You've found it. The one and only keyboard combination that hasn't been found yet. Typed by going row by row from left to right, hitting every-other letter starting from the top of each row to the bottom, then going back and filling in the missed letters, also following the top to bottom format.

Alternative versions: Zqscefbthmukoaxwdvrgnyjilp (Bottom to Top), plijyngrvdwxaokumhtbfecsqz (Right to Left), plkmuhbtfceszqoijnygvrdxwa (Bottom to Top, Right to Left)

I was so bored I discovered Zqscefbthmukoawxdrvgynjilp
