A little personal note, I use QED editor, is it your work?
People fond of MetaComco ED may forgive, I prefer QED :/)
Speaking of QED: I've been delving in the QED source and object files which have been around in my archives for 25+ years. The version 1.01 which was distributed (which you probably have) is the oldest stable version around but I've done more development after that. There is a stable version 1.02 which supports TK2 default directories (but AFAIK was never released) and even a 2.0 version which supports editing multiple files (but is probably not stable). I have to sort things out first but you can expect an announcement in the next days...
