STICKY KEYS

I held down the shift key to type something in CAPITAL LETTERS. I released it, but then saw that the letters were still in CAPS. The key wasn't stuck or anything but the internal signal seemed to be.

Every link I clicked opened in a new tab.

If I pressed any of the arrow keys in text areas, the text got highlighted :@

I had to use caps lock to remedy the unwanted capital letters and take it off to use caps.

Old-school-hitting-the-device-if-it-doesn't-work worked. MY shift keyboard is back to normal.
