a kind request for the Greek T9 (maybe for the "full versions as well, but don't know since I only use the T9 mode

The Greek quotation marks are not the english " ", but the guillemets « ».
So, I would be happy to
1. have («») on the top left corner of the T9 instead of the current ("), on the same key with the (-)
2. have them work smart, thus («) at the start of the quotation and (») at the end.
Thanks in advance,
Jimmy
