Right. But you're not the guy I was trying to teach! :) I was going on the
theory that it's better to teach someone to fish than hand them a fish.

By thinking about what Alignment 4 means (what is what I wanted to get the
OP to think about), one realizes (eventually) that the text position was not
caused by the paragraph being originally right-aligned (because it wasn't);
therefore changing the alignment won't affect it.

However, the beans now having been spilled, here's a possible version of the
desired fish:

- (NSAttributedString*) pageFooter {
NSAttributedString* s = [super pageFooter];
return [s attributedSubstringFromRange:NSMakeRange(1,[s length]-1)];
}
