>- a couple of times a year, lay out some newspaper on your desk, hold your keyboard upside down over it and beat vigorously all over the back of it. You will be amazed and appalled at the crud that comes out of it, especially if you don't follow steps 1 - 3 above
I use the variation where I vigorously shake the keyboard. My co-workers were looking at me as if I'd gone insane (because I jokingly state that I'm trying to reboot the computer) -- then they noticed just how much stuff came out and thought it was disgusting. One of them commented that it's just easier and better to simply use a vacuum cleaner like he does. I then did the same vigorous shaking thing with his keyboard and *more* stuff came out of his keyboard!
