On Windows, when I am typing in Hebrew, I can press Shift and a letter and get the English letter typed. This is very usefull as I don't have to change keyboard layouts all the time if I want to write mixed Hebrew/English texts.

On Mac, when I am using the Hebrew keyboard layout, pressing Shift and a letter does not do anything.

Is there any way to get Windows style functionality on the Mac?

I am using Mac OS X Leopard.
