dragAttrContext alsmost gave me what I needed, I could adjust multiple attributes with it and recall it as needed, but sadly it does not respect the channels box’s “speed” setting, the middle icon shown on the top right corner of the channel box.
it seems once dragAttrContext context is defined, it has nothing to do with the channel box.
In any case, the peformance concern I had with the getAttr/SetAttr did not bear out. I pllaning to design a method of adjusting attributes using hardware such as a hyperscroll wheel, shuttle whel, etc. But surprisingly enough Maya kept up…
Thanks for the help Mambo4.
