Hello,
As far as i know, it is actually impossible to scroll up and down the list of firewall rules :

Maybe it's possible with a keyboard but in order to modify a rule, we must have the focus on a selected element, i.e. we have to click on it (not possible by keyboard !!).
The problem is that we can not click on the last element of the list, so we can't have the focus on it, so we can not modifiy it.
I hope i am not wrong.
Can you tell me why we have to use a keyboard to scroll this list ?
NB : Windows 8 and some computers are designed without keyboard (touch screen).
