Can't type Hebrew letters in TextEdit

I just need to be able to type Hebrew letters in Final Cut Pro to do some Hebrew text animation. I thought I would first try to type them in TextEdit.

I tried the following method from Tom Gewecke's blog on Troubleshooting Language Problems, and it did not work for Snow Leopard:

'4. OS X - I Switched to the Font for Language X, but Can Only Type English: In a Unicode system like OS X, you switch keyboard layouts rather than fonts. Go to system preferences/international/input menu and check the box for the language you want, plus the box for "show input menu in Finder," then select the language in the "flag" menu at the top right of the Finder, and type. The font will take care of itself.'

The above advice correctly described the language menu for a Mac 10.5.8 laptop, like I'm using now. But on my imac, Snow Leopard has a different menu in System Preferences, called "Languages & Text", with different formats and an extra menu not described by Tom, above.

I tried to implement the above advice as best I could despite the menu differences. I also changed the "language of preference" to Hebrew. All that happened is, the next time I turned on the computer, the features in the "Language" section of System Preferences were all written in Hebrew titles. Nothing happened in TextEdit (even after I restarted the computer), where I need to write in Hebrew and not English, characters.

FYI - before trying all of the above, I installed the optional "extra fonts" and "language translation" features on the Snow Leopard OS X installation disc. I also installed a Hebrew keyboard and even the Ezra Sil fonts as instructed by Tom Gewecke, but I still can't type Hebrew characters in TextEdit.

What am I doing wrong?

Thanks.
