Thanks for weighing in on this, guys!  Turns out I was doing it wrong.  :\
I was selecting a handful of Layers and then trying to scale them up with the Transform Points tool, and not the Transform Layer tool.  The latter works MUCH better, and I don't have to put them in a group (which, by the way, doesn't work for Frame by Frame stuff, because once you take them back out of the group -to make them work as an FbF switch layer again- the resizing goes away, because it was done to the "group" layer and not the individual layers.  Let that make up for my previous incompetence.)
And yeah!  "Alt + the arrows" is what exactly I was looking for!  Now what is this "manual" you speak of?  
Seriously, thanks again.  I'll get this bird off the ground yet!
