In DenChart you can run the spell check to see if you have made any spelling mistakes. When you ask the program to help you correct your work, it reads through every word you have written and checks to see if the word is in its dictionary. If it isn’t, it shows you a dialogue box like the one you can see in the picture below.
Spell check will allow the ability to Ignore a word Once, Ignore All words, Add a Word to Dictionary (just make sure the word is spelled correctly). You can Change a misspelled word or Change All misspelled words. Close will close the spell checker out.
