No, it's part of the include file "xio.bb" of XLNT2. Probably there are minor version diffrences between mine and yours. This function is also used by other functions in the xio.bb file. Search for "scroll" in that file.
The docs say the official version of xlnt I am using is:
XLnt ii v1.2
So it's XLnt 2 subversion 1.2
