I'm currently going through St. John's college, and I have to learn/ read/ translate ancient Greek manuscripts. I just made the switch over to Ubuntu 6.06 from XP (although I have some SuSE knowledge from a few years back), and I'm not sure how to set up Office to allow me to type in in the Greek character set (including voicings, diareses, etc.).

Any suggestions? Also, is there a way to set up profiles in it so that I can write a normal letter, switch profiles and work on Ptolemy?
