5 The Keyboard Evolves Bimanual Control Split Keyboards Did you know? The number of keys on a keyboard varies per country. There are 104 on a standard flat keyboard in the U.S., 109 in Japan, 105 in Italy and 107 in Brazil. The keys on the original typewriter, developed by Christopher Latham Sholes in 1873, were arranged alphabetically. However, people became so adept at typing the keys would jam when hit in quick succession. Sholes rearranged the letters so the most frequently used keys were as far apart from each other as possible in order to slow down the speed of typing. His keyboard became known as the QWERTY keyboard, the standard key arrangement still used today. The average typist on a conventional QWERTY keyboard will move their fingers between 19 and 32 kilometres per day. Internet Buttons Go back and forward within Web sites on the Internet with a single touch. Scroll Wheel Scroll easily without using the on-screen scroll bar. Used in combination with the mouse scroll wheel, you can navigate using whichever hand is free. Shortcuts These easy-to-use buttons allow you to cut, copy and paste. The buttons were customised to fit to finger pad size when resting on the keys Application Switch Toggle between program windows with a quick touch. This key replaces the ALT+TAB method of switching between program windows. Honan, M., E. Serina, R. Tal, and D. Rempel, Wrist Postures While Typing on a Standard and Split Keyboard.
