In the lower right-hand corner, you should see an "En" icon. If you click on "En" you should be able to change to "JA" if your application is capable of typing in Japanese. If your application is not capable of typing in Japanese, you cannot see the "JA" icon.

After changing to the "JA" mode, you should see something like that at the right on the lower part of your screen. If you click on the right most icon (a book with a question mark), you will get a help menu.

This is how the help menu looks like.

As I wrote earlier, I'm a Mac user, and this is the best help I can give you to use IME.

If you have further questions, you should send your questions to Microsoft or the class.
