Greek Keyboard Tester

Every key shows its Greek and Latin letters as bilingual keycaps do, with the tonos dead key and the Greek question mark in place.

Tip: click a key in the picture if your keyboard doesn’t have it, so it doesn’t count against the score.

Chatter (double-typing) detector

A worn or dirty switch can register one press twice. Type normally for a minute, then press any suspect key 20–30 times.

Rollover & ghosting test

Best combination:
  • –

Hold down more and more keys (try ASDFJKL). If the count stops at 6 of these, the keyboard is 6-key rollover. Shift, Ctrl, Alt and Win don’t count toward that limit.

Timing tests

Put a flat hand on the keyboard so 4–8 keys go down at once, lift it, and repeat about 15 times, or drum your fingers across the letters. The keyboard sends each change with its next report, so the gaps between those key events step in whole polling intervals.

between key events

Press several keys at once to start.

Gaps between key events up to 10 ms, in 0.25 ms steps. A 1000 Hz keyboard makes peaks at 1, 2, 3 ms; 125 Hz at 8 ms.

The Greek layout

Greek keyboards are printed with both alphabets, and the picture draws them the same way: the Greek letter at the left of each key, the Latin letter small at the top right. Most Greek letters sit on the Latin letter with the same sound or look: Α on A, Β on B, Δ on D, Φ on F, Γ on G. The exceptions are the ones to learn: Θ on U, Ξ on J, Ψ on C, Ω on V, Χ on X, Η on H.

Two keys behave differently. Q types ; and :, where ; is the Greek question mark. W types ς, the final sigma. The key right of L is the accent key: a dead key for the tonos (΄), and with Shift the diaeresis (¨). The table under this text lists every key that differs from US, including AltGr symbols such as € on E, © on C and « » on the bracket keys.

Switching to Greek

  • Windows: Settings, Time & language, Language & region, Add a language, Ελληνικά. Switch with Win+Space or left Alt+Shift.
  • macOS: System Settings, Keyboard, Text Input, Edit, +, Greek.
  • Linux (GNOME): Settings, Keyboard, Input Sources, +, Greek.

Testing it

Press every key; each lights up under its Greek and Latin legends, the accent key too. If Greek letters come out as Latin ones, the computer is on English; in Chrome and Edge the line under the picture says so too.

The Greek keys at a glance

These keys differ from a US keyboard. The browser code is the name the key sends in the event log, taken from the US key in the same place. AltGr is the right Alt key; on Windows, Ctrl+Alt does the same. Keys marked "dead" type nothing on their own: press one, then a letter, for an accented letter (or Space for the mark itself).
