Changes to 0.6.1:
Graecise won't automatically put accents in front of capital Vowels (except the capital Rho) since this causes Problems words beginning with a diphthong, such as Europa.
Other news:
I created a project page that explains the use of Graecise and how to modify it a bit better. Mind you, it is not ad-free. Sorry about that.

As the macro is open source you're free to change it to fit your needs.
Please rate the extension if you like it (and if you don't; but I don't hope so) - I'm open to suggestions on how to improve the macro.
In order to properly use this macro you need a Unicode font with all necessary letters.
Examples:
Deja-Vu (free)
Linux Libertine (free)
Athena Unicode (free)
Arial Unicode (newer Windows/ MS Office versions have it)
And this is how it works:
You write a word in Latin characters, run the macro and the text will be converted to Greek.
Conversion scheme is quite straight forward - more so if you used Beta Code before.
Not so obvious letters are:
c becomes xi
q becomes theta
w becomes omega
y becomes psi
