Abstract
An apparatus for inputting opening and closing parentheses simultaneously by a single keystroke and method for the same are proposed. The keyboard is augmented with a parenthesis key. The opening and closing parentheses are simultaneously input by pressing the parenthesis key, wherein the key codes for opening parenthesis, closing parenthesis and cursor right are successively generated. Therefore, opening and closing parentheses are simultaneously input and cursor is placed between the opening and closing parentheses to facilitate typing.
