How do you type Theta on a Mac?
Γο το Συστεμ Πρεφερενψεσ/Λανγθαγε &amp; Τεχτ/Ινπθτ Σοθρψεσ, σεαρψη φορ Γρεεκ, αδδ ιτ.
Νος υοθ μαυ τυπε θ φρομ κευβοαρδ.


   Go to System Preferences/Language &amp; Text/Input Sources, search for Greek, add it. Now you may type u from keyboard.




Or you may just use Find and replace function in Edit menu to change ø to θ afterwards.
