Does that turn off all mouse function? I could make friends with
disabling the touchpad forever, but I would like to keep the mouse
stick (or whatever that little nob on my keyboard is called that moves
the mouse cursor if you push it).
I have a Dell Latitude E6520. Ironically, I can't open the list of
specs from the Dell website in Firefox to find out what kind of
touchpad I have.
Take care
