It is not possible to use Yahoo! mail to write emails in Hebrew, written from right to left, and embed Latin characters in the text. Since the text direction on Yahoo! is automatically left to right, the text combination of Hebrew and Latin characters becomes a big mess, and this is also the case when using commas, stops, etc. The solution for this in Word is the option to change the text direction from right to left. This must be true for other languages as well, such as Arabic.
