Automatic Spell Checking On/Off
Typing errors are highlighted in the document with a red underline. If you place the cursor over a word marked in this way, you can open the context menu to obtain a list of suggested corrections. Select a suggested correction to replace the suspect word with the suggestion. If you make the same mistake again while editing the document, it will be marked as an error again.
