Oh, that's what "ninched" means!
Way back when I mentioned " Temporal Ninching ", using "ninched" to refer to a mixed state checkbox. I just learned, thanks to Murray Sargent's blog , that NINCH is an acronym for " no input no change " I had the pleasure of working with Murray Sargent for a while when I was on the InfoPath , sorry, Microsoft Office® InfoPath™ team. At least at the time, InfoPath, Word and RichEdit were one big happy document-authoring family in the org chart. I confess that I don't remember the details, but we spent several hours discussing the finer points of text editing services.
