I have done "something" to my keyboard - wish I knew what! When I hit any the u i o j k l or m keys, instead of typing words I am typing numbers - 4 5 6 1 2 3 or 0. I know that this is a feature that can be turned on or off but how can I turn it off please? It's driving me bonkers! I have typed this by holding down the Fn key with my left hand and typing with my right.
