To control line highlighting you must adjust this variables. If bgColor, frColor is clNone, so line highlighting is not used. If you want to highlight only background, you must assign only bgColor.
If Selected is True, selection mark style will use inverted colors of line highlighting, otherwise it will use specified in TSyntAnalyzer style or default selection mark style.
