Spell Catcher Plus Thesaurus and Dictionary

You can look up a word in the English dictionary or Thesaurus anytime you want, but selecting "Lookup..." from Spell Catcher's menu. You will be presented with a dialog which shows you both the English dictionary and Thesaurus indexed to the word you've just typed or selected.

Here you can click on any word you presented in either the thesaurus or dictionary and use it to replace the word you've just typed or selected (energize, fortify, invigorate, reinforce). This can really help when you just know there's a better word than the one you're using!
