About Greek letters
Modern Greek uses one accent, the tonos, on the stressed vowel, and the dialytika (two dots) to separate vowels. The Greek question mark looks like a semicolon.
The Greek layout maps letters phonetically onto QWERTY (a = α, b = β, d = δ, f = φ, g = γ, h = η, j = ξ, u = θ, v = ω, c = ψ). The tonos is typed with the ; key before the vowel.
Final sigma ς is used only at the end of a word; on the Greek layout it is on the W key.
