Use AutoCorrect and Find and Replace
AutoCorrect
Word's AutoCorrect feature can assist you in word processing tasks. AutoCorrect can help you locate misspelled words and correct them as you type. AutoCorrect can also be customized so that commonly used words will be automatically entered without you having to type the entire word.
Examples:
When typing the misspelled word stannd, Word will automatically convert this typo to the correct spelling, stand.
Instead of having to write a long proper noun like GCFLearnFree.org, you can customize AutoCorrect to automatically complete the rest of the proper noun once you type the letters GCF.
