## Symbolic References Shown as Hyperized'' Text

In printed documents cross-references are shown through a numerical or symbolic indirection e.g. see Figure 1'' (numeric indirection), or see section Changes'' (symbolic indirection). LaTeX2HTML can mirror this mechanism using the same numeric or symbolic references, or when these are not appropriate by using iconic references.

In a hypertext document however, cross-references can be shown without any indirection just by highlighting a relevant piece of text. This can make a document more readable as it removes unnecessary information.

A single new LaTeX command hyperref can be used for specifying how a cross-reference should appear both in the printed document and in the hypertext version.

Assuming that the label sec:cond is defined somewhere in a document the command hyperref which takes 4 arguments can be used in the same document as follows:

\emph{Is the concept of
\hyperref
% This will be highlighted in the hypertext version
{conditional text}			% argument #1
% This will be shown in the printed version
% followed by a numeric reference ...
{conditional text (see Section }  	% argument #2
% ... followed by this text
% This the common label
{sec:cond}				% argument #4
a good idea? }

Here is how it will be shown:
Is the concept of conditional text a good idea?

In the printed version what would appear is:
Is the concept of conditional text (see Section XXX for more information) a good idea? Another command also defined in html.sty is htmlref which has the same effect as hyperref during the conversion to HTML. It takes two arguments, some text and a label. In the HTML version the text will be hyperized'' pointing to the label. In the paper version the text will be shown as it is and the label will be ignored eg

With \texttt{htmlref} \htmlref{it's easy to make links}{fig:example}.

In the HTML version it will be shown as:
With htmlref it's easy to make links.
