I ran into a problem where everything I typed appeared as if I was holding down the [SHIFT] key. This of course was false, and cause all sorts of problems. Even mouse clicks appeared as if I was holding down [SHIFT] prior to left clicking.
To remedy, I found a simple key stroke combination.
Holding down the right [SHIFT] key, I pressed the [CAPS LOCK] key. After releasing both keys, everything appeared to be in good working order.
