Additional features of Greek Tonizo for Windows, Mac, Linux
Greek question mark: Same position as in English - so that bilingual users are not confused.
Characters "lost" to the additional accents (the two square brackets and the single quote): They are produced when a space, not a vowel, is keyed after a perispomeni, psili or vareia.
The symbol of krasis (koronis): use psili instead, i.e., τοὐλάχιστον.
Apostrophe: Vareia, converted into single quote, is used instead, i.e., σ' αὐτόν, γι' αὐτό, κάψ' το, πᾶρ' το, ɑ' μέρος, Α' τμῆμα, Β' κεφάλαιο, etc., just as in the monotonic keyboard.
Initials: Greek Tonizo does not place a breathing on single, non-accented, uppercase vowels followed by a fullstop, i.e., Ε.Ε., Η.Ε., Α.
Initials without fullstops, i.e., ΕΕ, ΟΗΕ, are keyed with CAPS LOCK on.
Initial vowels without breathing π.χ., "-α", are keyed with CAPS LOCK and SHIFT.
