The research pane also has some options to translate documents. The easiest way to translate a word, sentence, or phrase is to select it in Word, and then right-click and click Translate.

Once you do this, the translate options will appear in the research pane:

Use the first two drop-down boxes to choose what language your document is currently in (From) and what language you want it to be (To). Note the warning that your document will be sent over the Internet in an unencrypted format.

Then, scroll to the bottom of the pane and click the green arrow to open your results in a new Internet Explorer window.

Depending on your text, there may be a translation right in the pane, as there is in the example above. (Note that this has been machine-translated so it may not be exactly correct.)

Conveniently, there are links for paid translation services right in the pane. If you scroll down further, you can also see more translation options. These options allow you to research in different areas to obtain different results.

You can also click on the Translation Options link in the middle of the task pane (just below the green arrow) to open this dialog box:

You can use this dialog box to choose which dictionaries to use, whether or not to use online machine translation, and what language pairs to make available. You can use the drop-down menus in the bottom half to choose the translating service for each language pair. (As of this writing, WorldLingo is the only service listed in those menus.) 

Once you’re done setting your translating options, click OK to go back to your document.
