Not without extensive use of Javascript, which I avoid like the plague for a plethora of reasons.
I'm with you on really liking WordStar stuff, though. I prefer to use PrimalScript 2.2 instead of 3.0 for development work mainly because 2.2 still supported WS keyboard shortcuts, which all of us old geeks have memorized. It was the standard (aside from WordPerfect) in the pre-Windoze days.
