Using an English keyboard in symbol font, you can make a fairly accurate reproduction of a Koine (or Classical) Greek text. The following list of Greek letters can be typed using the symbol font. The line of phonetically spelled letters (below) are followed by the keys on an English keyboard which correspond to each symbol keystroke. Upper and lower case work in the same way as on an English keyboard.
alpha, beta, gamma, delta, epsilon, zeta, eta, theta, iota, kappa, lambda, mu, nu, xi, omicron, pi, rho, sigma, tau, upsilon, phi, chi, psi, omega
A, B, G, D, E, Z, H, Q, I, K, L, M, N, X, O, P, R, S, T, U, F, C, J, W
Notice that a final sigma must be keyed differently than a regular one. If you have taken Greek, you will remember that when a sigma occurs as the final letter in a word, it is written differently–it actually looks a bit more like an English “s”. A final sigma can be typed by keying a capital vee (V) while in the symbol font.
Aspiration marks can be made with single apostrophes (pointing the right direction) in whichever font suits the look you want. Happy writing!
