I do usually switch over to a Unicode Hebrew keyboard, but there are times when it is just faster to use Logos' untransliteration feature. (I.e., start a search with g: or h: and it will untransliterate to Greek or Hebrew.)
No problems with Greek, and the wiki has a Greek Untransliteration Keyboard.
Hebrew is a different matter. I can't find a similar Untransliteration Keyboard. In particular, I cannot figure out how to get a tsade or ayin.
Thanks for any help.
Note: I thought tsade might be "x" or "c" but for some reason those do not untranliterate, and you get English suggestions.
