How's this : μηδέν ? I used the :/; key to get the sharp accent but it doesn't work with BYKI. Perhaps I should ask the owners of that software for the solution? How do I get the grave accent? ὲ Is this right? I used ] + ε . Ι think it worked! Thanks. I downloaded kipepola.msi from http://www.polytoniko.org and installed it as suggested by you and them. ά έ ὰ ὲ ί ὶ ή ὴ
