This sounds more likely. I was definitely playing around with NSLayoutManager at some point. I’ll look into that, but if anyone has any ideas how one would get the effect I’m after using NSLayoutManager I’d be grateful for the heads up. > If you need less complex layout features, you could also do it using Core > Text.

That might be one way to go. I’m pretty sure when I “discovered” this effect, I was able to manipulate the timing (because at first I thought I’d use it, but I wanted it faster), but I’m pretty sure I didn’t know how to use timers in those days. Still, I’ll look again into this approach. Thanks for all your insights, Graham. Much appreciated!
