The program is activated by holding down CTRL and right-clicking on a word in almost any program. This opens the WordWeb main window, with definitions and other help. The program usually resides in the tray.
Phrase guessing – for example, CTRL + right-clicking on the 'Princeton' in 'Princeton University' will show the meaning of the combined entity rather than only 'Princeton'.
Words from pictures – CTRL + right-clicking on a word within an image will ask WordWeb to guess the word.
