hidden
{class:text style info, on styles:{plain, all caps}, off
styles:{bold, italic, underline, outline, shadow, condensed, expanded, hidden,
strikethrough, superscript, subscript, superior, inferior, double underline}}
hidden is a text-style constant that represents
the hidden style in a text-editing application such as AppleWorks.
Some applications return text values that encapsulate the style
information, such as font or point size, instead of leaving it as
plain ASCII text. See all caps in this section for
a further discussion.
