Logos has released Shibboleth, an interesting Greek/Hebrew text-entry program to the general public. While it’s not very useful for a Greek student who needs to know how to key in Greek text directly into a word processor, it could be helpful to someone who needs to do an occasional one-off in Greek without needing to install a Greek keyboard. Unfortunately, I haven’t been able to figure out how to use the program with my Greek keyboard layouts–it seems you are obligated to use the keyboard layout that comes with the program.
