The Microsoft Word Spellchecker

If you have "Check spelling as you type" switched on, you should have red wiggly lines under three of the words in your letter: counsil, libary, and decicion. Microsoft Word has a spell checker that you can use to correct any misspelled words.
To launch the spell checker you can either click on Tools, then select Spelling and Grammar Or just press the F7 key on your keyboard.
You can have Word check the entire document for spelling mistakes, or you can check the spelling for selected areas. To check the spelling of a selected area, you first have to highlight the text you want Word to check. Next, click Tools > Spelling and Grammar. Or just press the F7 key.
To check the entire document, just go straight to Tools > Spelling and grammar, or press F7. You'll get the following dialogue box:


There are two main areas of the dialogue box: Not in dictionary, and Suggestions. The text box below the words "Not in dictionary" shows part of your text, and one spelling mistake at a time. The spelling mistake is in red.
In the text box below the word "Suggestions" are alternatives to the word you got wrong. In the image, you can see that three alternative words are suggested for counsil: counsel, council, and counsels. What we really meant was, of course, council. So we want to change counsil to council. To make the change, do the following:

1.Click on the word "council" in the Suggestions text box
2.Click the Change button
3.Word moves on to the next word you got wrong


The next word we spelled wrong is now highlighted in red: libary. As you can see, Word is giving us two alternatives in the Suggestions box: library, and liberty. The correct spelling was library, and this is already highlighted in the Suggestions box. So we can just go ahead and click the Change button.
Microsoft will move on and pick our third misspelled word: decicion. Make the changes to your letter so that the correct word is inserted. When the spell check is complete, the dialogue box will vanish. You'll then get a message box telling you that the spelling and grammar check is complete. Click OK to get rid of the message box.
