Get all items in branch using split tree

[Stroopwafelandcoffee]

I have contoured a number of curves and am left with a few spurious points in the third branch of the tree. I’m basically trying to ‘cut off’ the last branch. I’m trying to use split tree and then select the right items using either:

{0:all:0}
{0;range;0}
But I’m unable to find the correct notation for ‘all items in this branch’ or ‘range of items in this branch’.

Are you looking for Trim Tree?
Not quite sure which list items/branches you’re trying to get rid of.

I’m trying to get rid of the last branch. As far as I know trim doesn’t allow this? I’m not able to reduce my list to 281 points using it

Thanks! That’s an oddly verbose way to go about it, but it does work!
