One-click look up (using the mouse)

Hold down the Ctrl key, right click with the mouse on the word you want to look up
You can change the keyboard-mouse combination using the item on WordWeb's Options menu.
WordWeb will automatically look at the word you clicked on and surrounding words, and look up the longest phrase, collocation, or word in the database. If the automatic selection is not correct you can chose another combination of words by using the drop down arrow in the WordWeb window.
