Moving to a specific column (with a cons argument to > vertical-motion) seems to be less of a problem. If that's in a continuation line, you have the same problem: the display engine and the move_it_* functions count coordinates and columns from their BOL, not from your "actual" BOLs. > (By the way, have you tried the code at all?) No, because I don't know how much I need to just see the problems, without the solutions. At some point I will probably ask you for a minimal patch an a recipe to see the problem, unless we will find a solution by just talking.
