Harrie, I can't type would, could, or should correctly to save my life, but I can't type not either -- I wuold (see?) have to make these wont, cont, and shont....
and I can't even put in ont to correct to not because, of course, ont is the abbreviation for the province I live in! maybe I'll go with an earlier suggestion (can't remember whose) and use nn for not, then wnn, cnn, and shnn (and hope none of my patients fall off the couch and dislocate a shoulder while watching the news....) LOL
Off to update the dictionary!
