As you type in Microsoft Word, take care to notice when the computer puts a red squiggly line underneath a word you typed. If you see a red squiggly line, the word is spelled incorrectly. If you right-click on the word, MS Word will show you a list of correctly spelled words that it guesses you were trying to spell. If you wish to check the entire document, you can click the Tools tab at the top of the page and then spell check. This will go through the document and point out every misspelled word or grammatically incorrect phrases. You then have the option of changing to what MS Word thinks you were trying to spell or clicking ignore and leaving the word the way it is.
