How is the Greek layout arranged?

The modern Greek layout maps US QWERTY positions to Greek letters, mostly phonetically: a gives α, b gives β, d gives δ, and so on. The final sigma ς sits on the W position, which is the one mapping most people forget.

How do I type an accented vowel?

The tonos accent is a dead key on the US semicolon position. Press the semicolon key, release it, then press a vowel to get ά, έ, ή, ί, ό, ύ, or ώ. The accent only appears once you type the vowel.

What is the dialytika and how do I type it?

The dialytika is the diaeresis, the two dots over ϊ and ϋ that show a vowel is pronounced separately. It is produced with Shift plus the semicolon dead key, followed by the vowel.

How do I type letters with both tonos and dialytika?

Greek has two such letters, ΐ and ΰ. They are built with the combined tonos-and-dialytika dead key, typically Shift plus AltGr on the semicolon position, followed by ι or υ.

The modern Greek keyboard places Greek letters on US QWERTY positions, mostly by sound, and handles accents through dead keys. This reference shows the full map and explains how to type the accented vowels with the tonos and dialytika.

How it works

Each US key position carries a Greek letter, largely phonetic: a=α, b=β, d=δ, f=φ, g=γ, h=η, and so on. The final sigma ς is on the W position and the regular sigma σ is on S. Accents are added with dead keys: the tonos ΄ is a dead key on the US semicolon, so pressing ; then a vowel yields ά έ ή ί ό ύ ώ. The dialytika (diaeresis) for ϊ ϋ uses Shift plus the same dead key, and the combined tonos-plus-dialytika builds ΐ and ΰ.

Example

To type the word ώρα you would press the semicolon dead key, then the V position (which carries ω) to get ώ, then the H position for ρ… — note the layout is phonetic but a few letters such as ξ (J position) and ψ (C position) need to be learned individually.

This covers the monotonic Greek used in everyday writing. Reference-only — it explains the layout and dead keys but does not remap your keyboard, and it runs locally in your browser.
