If you start renaming a file (e.g. by clicking f2 with it highlighted), and scroll, the textbox for entering entering does not scroll along with the file list, instead remaining in the same spot in the window. I supposed something like this would be required if you scroll enough that the file you're renaming goes outside the window though, so it's not entirely avoidable.
