It is difficult to type $&*^(*&)(* with the left hand only - or is it ?
±!@£$%^&*()
All typed with my left hand with fifth on left shift, not tricky and no stretching required.
Maybe you need to get her one of those finger exerciser thingies.
Otherwise, yes, as others have mentioned, sticky keys. You should be able to turn it on via 5 shift key presses... no need to visit the control panel.
