When you click a link in the OmniHelp search results list, by default each term found in the target topic is highlighted in yellow.
To turn off search-term highlighting, or change the style:
[OmniHelpOptions] ; UseSearchHighlight = Yes (default, highlight search terms found) ; or No UseSearchHighlight=Yes ; SearchHighlightStyle = style to use in span to highlight search ; terms found SearchHighlightStyle=background-color:yellow;
The highlighting style consists of one or more CSS property:value pairs, each followed by a semicolon. Consult a CSS reference for possible styles.
