List.scan<'T,'State> Function (F#) needs additional keywords

in the real world this function sounds like a running total or cumulative sum.

How would I find this List.scan page as a solution when searching for either of these terms?

If you create something new, that's fine and great, but you gotta say what its similar to, or the same as in the old terms or no ones knows.
