%D As long as there a natural feeling of what can be considered
%D hyper active or not, we have to tell users where they can
%D possibly click. We've already seen a few macros that deal
%D with this visualization, something we definitely do not let
%D up to the viewer. One way of telling is using a distinctive
%D typeface, another way is using color.
%D
%D There are two colors involved: one for normal hyperlinks,
%D and one for those that point to the currentpage, the
%D contrast color.
\definecolor [interactioncolor] [r=0, g=.6, b=0]
\definecolor [interactioncontrastcolor] [r=.8, g=0, b=0]
%D The next few macros are responsible for highlighting hyper
%D links. The first one, \type{\showlocation}, is used in those
%D situations where the typeface is handled by the calling
%D macro.
%D When we're dealing with pure page references, contrast
%D colors are used when we are already at the page mentioned.
