The Greek layout maps Greek letters onto their nearest Latin counterparts: Ε Ρ Τ Υ Ι Ο Π sit under E, R, T, Y, I, O, P, and Α Σ Δ Φ Γ Η Κ Λ under the home row. Letters without a Latin twin fill the gaps — Θ under U, Ξ under J, Ψ under C, Ω under V — while Q types the Greek question mark ; and W the final sigma ς. The key right of L is the tonos accent, a dead key you press before a vowel. Keyboards sold in Greece are usually ISO boards with a tall Enter and a < > key beside the left Shift.
The tester reads physical keys, so it works whether Greek or English input is currently active. Press every key and watch it light: the keycaps show the Greek letter with the Latin letter in the corner, so you can find each one either way. Press the tonos key on its own — it registers immediately even though nothing appears until the next vowel. Check the ISO-only < key beside Shift.
Greek input is toggled with Alt+Shift (or Ctrl+Space on macOS). If letters come out Latin the system is simply in English mode; the keyboard is not faulty, and every key still lights up correctly here because the tester ignores the produced character.
