Ok now this is crazy!! I picked it up to check the button between the contol and alt and now the keyboard that was not letting my type is now fine. But I still don't know why it wasn't working yesterday.
The button between the control and alt on the left is the start button and on the right is the same as right clicking my mouse.
I give up! If it happens again I guess I just wait and it will revert to normal given time?
