(because the original was typed with hands shifted left).
t (right of t is y) — no, that’s not matching. Let’s test a known phrase online: “thmyl fylm” decodes to “signal film”? No. thmyl fylm zym sabt
Known trick: If you type a word while your hands are shifted one key to the left on the keyboard, you get this effect. For “signal” typed with hands shifted left: s (right hand shifted left) → actually, let’s map correctly: (because the original was typed with hands shifted left)
Take “thmyl” — if the coder meant to type “signal” but their hands were one key left, then to decode we shift each letter one key : thmyl fylm zym sabt
