When checking spelling on a form:
From a form that supports Spell Checker, click Spelling to open the Check Spelling on Forms window.
You can enter the correct word directly in the Change To field or select it
from the Suggestions list.
Ignore and Ignore All are effective only for the form you are currently
working in. If you find yourself clicking either button repeatedly for the same
word, consider adding the word to the dictionary by clicking Add. The spell
checker will then always bypass that word.
In the "Ignore words with" area, you can tell Spell Checker when to skip special spelling
