A family of Microsoft word processing software products for creating web, email, and print documents.
The inverted question mark is Unicode character 00BF. You can use Insert | Symbolto find and insert the symbol, or you can type 00bf and press Alt+X, but you don't have to do either because Word has a built-in keyboard shortcut for this character: Alt+Ctrl+? (that is, Alt+Ctrl+Shift+/).
The inverted exclamation point is U00A1 or Alt+Ctrl+! (Alt+Ctrl+Shift+1 on U.S. keyboards).
