-
a three-stage process on a heavy spotting control. It runs in this fashion.
"Get the idea that you can have that (object)."
And when this is relatively flat,
"Get the idea of making that (object) remain where it is" (or continue where it is)
and
"Get the idea of making that (object) disappear."
This is actually a very fine process and undercuts (runs on a lower case than) trio itself.
