To make getchar() work inside the function that's evaluated for an <expr> mapping the typeahead needs to be saved, reset and restored later. Thus the function can't get any typeahead. This can't be changed, because recursive use of the function that gets characters is not possible. I think this is actually what most people want to happen. If you want to pass something tot he function you can give it an argument. -- >From "know your smileys": ...---...
