Using the 'Find Word' feature you can quickly find words matching a pattern. You can add your own technical glossaries (or list of company acronyms, etc) using the option on the 'Glossaries' menu. You can also get optional third-party dictionaries, including the Oxford, Chambers and Collins dictionaries, shown on separate tabs like the web references. Wikipedia and some online dictionaries are installed by default. The list of tabs can be customized to use your favorite references. Each reference is on a separate tabbed page for easy cross-referencing. In addition to using the comprehensive English dictionary and thesaurus supplied, if you are online you can also search your choice of web references. For example if you look at the similar words, maybe you'd like to see words that are more loosely similar: you can do this by pressing the '+' button, and go back again by pressing the '-' button. Related words also have '+' and '-' buttons to be more or less specific. You can also use the back and forward buttons.

To see the definition for one of the related words double-click on the word. Browsing around related words is simple: click on the tabs for synonyms, antonyms, parts, part of, types, type of, similar, see also, and anagrams. To look at a particular sense you can click on the sense number. If you are looking for a particular part of speech you can click on the Noun, Verb, Adjective or Adverb buttons to show only the relevant synonyms and related words. Look up using Ctrl+Right click on a word in almost any program. WordWeb has the option to highlight widely used synonyms, great for helping you write clear easy-to-understand English. If you are editing a document you can select a synonym and replace the look-up word. The hotkey can be customized, or you can use a keyboard shortcut if you prefer.

If you are online, with one extra click you can also search web references, for example Wikipedia. WordWeb Pro can look up words in virtually any program with just one click: just hold down the Ctrl key and right-click on the word.
