reactivating touchpad without using mouse
On my Fedora 18 x64 distro (running cinnamon), I accidently clicked on the button to turn off the touchpad when trying to fix another problem. The mouse froze instantly. Is there any key combination that will turn it on again without buying a mouse to fix it? I can get ito KDE, so if there is no mouse combo, is there any command that I can execute to turn it on again?
