How do you type greek letters?
By holding down letter keys in the keyboard, you get a choice of various accented Roman letters. By holding down the spacebar, you get a choice of language options.
I can't find any way to get Greek letters though. Is it possible to type these?
On similar note, there are lots of other alphabets missing (Arabic, Cyrillic, etc.). Is it possible to type arbitrary unicode characters? Maybe using \uxxxx codes?
