OT: touchpad with scrolling capabilities

[Santiago Erquicia]

I know that this doesn't belong to this list, but I would like to know
where should I mention this.

I have a new Toshiba notebook and one thing that I really like about my
touchpad is that if I move my finger at the right part of it upwards or
downwards it scrolls the windows up and down.  If I do the same, with my
finger at the bottom part and moving to the left and right, it scrolls
horizontally the window where I am.

Does anyone know who should I comment of this functionality?
