I'm trying to offset a bunch of referenced channels
So, for example, in the TX of a translate sop named "xform2", I'd put
So I'd like to append something to that reference to offset it by x
number of frames.
Similar to if I wanted to shift the whole curve up in value by 4, I
ch("/obj/null1/xform1/tx") + 4
But I want to shift the curve in time here.
I hope that makes sense. But it probably is something very simple I'm
