I have a curve, I clone it (copy-inplace)
I place two points on it as cut points
I selelect trim
I select the two points, I wish to trim away the one curve outside of the two points
I select the line to the left of the first, I get a choice, both of course say the exact same thing, lets attack the curve that is the higher of the two in my choice list.
I then select to right of the other point and again pick the upper of the two choices.
I discover that my line I was attacking had now become the lower of the two choices.
Is there a logic to the list, most recent at the top, but trim once and it goes to the bottom ?
