The one that comes to mind for me is WordStar, a ground breaking word processor from back in the character-mode CP/M & DOS days. It didn't successfully make the jump to graphical environments. They got killed by WordPerfect and MS Word.
Pioneered the use of the ESDX 'diamond' for cursor movement (when the Ctrl key was held down). Way back then keyboards didn't always have dedicated arrow keys. Made far more sense to me than Vi's HLJK scheme.
I just threw out an old manual/floppy box from the 80's that I had kept around for nostalgia reasons.
"ESDX 'diamond' for cursor movement (when the Ctrl key was held down" can you clarify what this means? Also whats stopping someone from writing an addon for wordperfect to do the same?
