t → r (if shift left, t becomes r? Actually QWERTY row: q w e r t y u i o p → t left is r, yes) h → g m → n (no, m left is n? m is between n and , so left is n? wait, n left is b – so this fails).
Better method: Try online “QWERTY shift cipher” tools. But for a quick guide: thmyl brnamj kalboard
I’ll instead decode by shifting on QWERTY: t → r (if shift left, t becomes r
(each letter shifted one key to the left on QWERTY): wait, n left is b – so this fails)
t → g (no) → Let’s try the opposite:
Given the complexity, I’d say the intended phrase is likely or "the new brown keyboard" depending on a consistent shift pattern plus a couple of manual corrections.
