Actually known puzzle: "fyltr shkn ntrw danlwd az gwgl" decodes with (each letter replaced by key to its left on QWERTY):
f (left of f is d) y (left of y is t) l (left of l is k) t (left of t is r) r (left of r is e) → “dtkre”? not a word. But maybe the phrase is backwards?
Try “s h k n” s (row2) → a h (row2) → g k (row2) → j n (row3) → b → “agjb” still gibberish.
But common keyboard shift cipher is on QWERTY:
But actually I think it’s (each letter replaced by key immediately to its left, same row). Let me decode fully:
Row 3: z x c v b n m Left shift: z→(none), x→z, c→x, v→c, b→v, n→b, m→n
