Word 2007 automatically proofreads your document for spelling, grammar, and style errors as you type; you can correct the errors as they occur or at the end of your Word session. You can customize how Word proofreads your documents by setting the desired proofreading options before you work on your document.
For example, suppose you want Word to make suggestions before automatically changing a misspelled word, as well as identify gender-specific words in your text. Follow these steps:
Under When Correcting Spelling And Grammar In Word, click the AutoCorrect Options… button in the right pane.
When you are ready to proofread your document, click the Proofing Errors button in the status bar to sort through and correct any errors that Word has found.
