(progn (insert "foo bar zot") (put-text-property 2 3 'face nil) (put-text-property 5 6 'face 'bold) (goto-char (point-min)) (goto-char (next-single-property-change (point) 'face))) This goes to 5, not to 2, so `next-single-property-change' doesn't seem to consider a nil value to be different from a missing value, either. So I think it might make sense to just leave that complication out of this function, because it's rather obscure (categories and stuff that sounds way too complicate :-)). -- (domestic pets only, the antidote for overdose, milk.) bloggy blog: http://lars.ingebrigtsen.no
