Thanks to Jonathan Fletcher, Bruce Herbach, Miki Eff, and Mike [NLN] (and possibly others whose e-mails I neglected to save) for advice and encouragement on how to highlight the currently active record in List view.

As advised, I used the OnRecordLoad script trigger. It was easy! It works slick! I am tickled pink. (Been looking for years for a way to do this.) My user is pleased. Other users soon will be.

In reading up on script triggers (which I never really got to know when they 1st came out back in FMP 10), I realized that there are many more possibilities that I haven't been taking advantage of. New horizons open up.

Next round's on me.

Thanks, guys!
