SEDF

The traditional FPS video game controls for QWERTY keyboards are centered around the W, A, S, and D keys, called "WADS" or "WASD". Moving them over one row to the right centers on the E, S, D, and F keys, pronounceable as "SEDF".

It's hard to play this game; I use SEDF, but it's hardcoded for WASD!
