Twenty-five years as a technical communicator and until today, I thought that you needed to buy a special "Dvorak keyboard" to type with the vaunted Dvorak keyboard layout. As it turns out, however, the Dvorak layout is built in to every major operating system. You can enable it in less than a minute, and then easily switch between Dvorak and QWERTY any time after that as needed. You can use the keyboard you have right now for either layout.
Don't know the Dvorak layout? No problem. You can print out a simple quick-reference card and tape it somewhere near your monitor. There's no need to re-label your keys, because you should not be looking at them anyway. And if you get frustrated or need to do something in a hurry while you are still learning the layout, you can instantly switch back to QWERTY when needed.
Has your curiosity been piqued? You can learn more at DVzine.org. (And yes, this blog entry is my first attempt at writing anything in Dvorak.)
