Nancy,
What in layman terms (for us techno challenged folks) does the y key do. And if you have the time, (seeing as how you aren't posting on the "Pass The Ball" thread) perhaps you could elucidate upon what the 4,5,1,2,& 3 keys do? Eternal gratitude forthcoming.
Thanks,
Myron
Edit:
In re-reading your last post, maybe I partially understand 4 & 5. I comprehend "along a spline" but across a spline throws me a little. 1,2 & 3 constrains movement of a CP to x, y, or z axis only, right?
