When chatting on the Internet or sending e-mails, you can use emoticons to express shock, surprise or other reactions. Emoticons are letters or punctuation signs which, when typed together, create a facial expression. While some applications allow you to select and insert emoticons by using a special menu, you can also type one simply by using the characters on your keyboard.
Open the document, e-mail or chat window in which you want to type the "surprised face" emoticon.
Press the shift and ":" keys on your keyboard at the same time to insert a colon.
Press the "-" key to insert a dash.
Press the shift and "o" keys at the same time to insert a capital O. You have now created ":-O" showing a shocked or surprised face as your emoticon.
