To translate text, OneNote 2010 offers translation services in the Research task pane as well as a little device called the Mini Translator. To translate text with the Mini Translator, all you have to do is select the text, hover the pointer over the text, and read the translation in the Microsoft Translator toolbar. However, you have to do some setup work before you can use the Mini Translator.
You can translate text not just from English to a foreign language but also from one foreign language to another.
Drag to select the word, phrase, or passage you want to translate (if you want to translate a single word, you need only to click it).
Click the Review tab.
