The research task pane is a proofing tool that allows you to look up words in the dictionary and thesaurus. It also can translate words and sentences plus look up words using encyclopedias and the search search engines Bing. Find the research task pane by clicking on the Research (Review tab–>Proofing group). It is located right next to the Spell Check button. Once you have the research task pane open, type the word you want to research. Click the top drop down list to change the purpose of the search. Example: to use the translation feature instead of the dictionary.
Tip: When in Word or Outlook, ALT+ left click a word that you want to look up. The research task pane will display with the word already typed out.
