Obtaining Path Count

How do I obtain the path count of a tree?

Seems like a simple question, but I can't figure it out.

I was hoping for a component like "Tree Length", similar to "List Length", but it doesn't exist.

I found path mapper's "you can use path_count" line so I suppose it can output it, but there is no indication how to correctly input data into the lexer combo editor.

Thanks for help.

EDIT: I used "Tree Statistics" and then "List Length" on my tree, which works. Happy to hear other suggestions though.

EDIT2: Right, my method doesn't work in that I cannot use it to retrieve the last path in a tree on which I want to perform a certain operation. I wanted to feed the value of the tree statistics path list length into the "Branch" component, but it needs the value in { } apparently ...

EDIT3: Okay, I feel like an idiot now :) Just had to add an L-1 expression to the List Length component and "Tree Branch" will happily accept it.
