The pen alone can * only simulate a one-button mouse. * To simulate a more-button (five, in this case) mouse, we use the four * keys along the the bottom of the iPaq as modifiers. * When one (or more) of the modifier keys is (are) down, a pen-down event * causes the corresponding bottons to go down. If no modifier key is * depressed, a pen-down event is translated into a button-one down event. * Releasing the modifier keys has no direct effect. The pen-up event is * the one that triggers mouse-up events. */
