In a similar way, <TeXmacs> provides tags for alternate views: depending on
whether a certain predicate is met, we show the ``main content'' on certain
overlays and the ``alternate content'' on the remaining overlays. We use
the same four types of predicates:
<\description>
<item*|<subsubsubmenu|Insert|Fold|Overlay|Alternate from here on>>The
alternate text will be used on this and all subsequent overlays.
<item*|<subsubsubmenu|Insert|Fold|Overlay|Alternate until here>>The
alternate text will be used on this and all previous overlays.
<item*|<subsubsubmenu|Insert|Fold|Overlay|Alternate only here>>The
alternate text will only be used on this overlay.
<item*|<subsubsubmenu|Insert|Fold|Overlay|Alternate except here>>The
alternate text will be used on all but the current overlays.
</description>
<TeXmacs> finally provides a means of customizing the way that ``hidden''
and ``shown'' content should be rendered: user determined coloring schemes
can be used using the <markup|alter-colors> tag which can be inserted from
<menu|Insert|Fold|Overlay|Specify color alternation>. For instance, in
order to achieve the effect mentioned in the example from
Figure<nbsp><reference|red-x-fig>, you may specify a ``black to red'' color
alternation, and then use a <subsubsubmenu|Insert|Fold|Overlay|Visible from
here on> type of overlay.
