How many times have you written an explanation or comment in parentheses and forgot to use the closing parenthesis? Some punctuation marks come in pairs. Excel will tell you it found an error in the formula if you don’t have matching parentheses. And Excel will offer a correction. The closing mark--quotation mark, parenthesis, or bracket--is easy to overlook.
In Word, use the Find command to help you. Press CTRL+F; type the beginning mark in the Find what: text box. Press ENTER to search the document. That way, you’ll find the beginning mark to see if its companion mark was typed.
