Both the Swing KeyStroke and AWTKeyStroke classes have docs like

    /**
     * Returns a shared instance of a KeyStroke that represents a key press and
     * release (i.e., a KEY_TYPED event).
     *
     * @param keyChar the character value for a keyboard key
     * @return a KeyStroke object for that key
     */
    public static KeyStroke getKeyStroke(char keyChar) {

Actually, this is not correct. KEY_TYPED events don't necessarily require
a press and a release; most of the time they are one or more presses.
