Keyboard folding is a good technique that can be used even in the work place when high levels of
computer rage must be done away with quickly. This technique requires no tools, but we recommend
a wire cutter to cut the keyboard wire instead of simply unplugging it. Take the keyboard, put
books under it on both sides to support it, and drive your foot down into the keyboard thereby
'folding' it in half.
