Including special text characters    

You can use control codes to overscore or underscore text or to include special characters. Both overscore and underscore can be active at the same time. To include control codes, as you type text, type two percent symbols (%%) followed by the special control code or character. A single percent sign is treated as a normal text character. A triple-percent control code is provided for those instances where a control-code sequence must follow a percent sign in the text.
