    <para>
        The macro takes the next character typed after macro execution
        as the character being searched.  That character is not
        displayed.  If the character does not appear in the balance of
        the current line, no action occurs.

        This macro illustrates the use of
        <function>InputHandler.readNextChar()</function> as a means of
        obtaining user input. <!-- See <xref
