1) Hold down both shift keys.
2) Type "THE QUICK BROWN FOX JUMPS OVER THE LAZY DOG" while shifts are down.
3) Post what keyboard you have.
If letters do not appear, or spaces, do not correct it- that's the point of the thread.

Basically, it saves the company of the computer ~0.0006 cents per key if they use some cheaper setup for the keys, but then it causes other keys to jam if pressed at same time (aka, the less letters you get typed, the cheaper your keyboard manufacture is )
Please post what keyboard you use as well.
I get:
QUICK BRO FOX JUS OVR LAZ DOG
I'm using some ultra-thin (9mm) Logitech keyboard.
