By default, hotspot text is green and underlined. To leave the appearance of hotspot text as is in WinHelp, set the following option:
;UseGreen = Yes (default) or No (remove green color from all links)
When UseGreen=No, hotspot character formats to which you have not assigned jump or pop-up properties in [HelpStyles] retain their original appearance. If you have assigned such properties, when UseGreen=No some automatically generated links appear underlined, but retain their original text color.
