This keyboard is designed for computer users whose applications involve extensive use of the Tab key and want an otherwise conventional keyboard layout and design. The extra triple-width ZTab key is located where the left, down and right arrow keys are located on the keyboard and generates the same key codes as the standard Tab key on the left edge of a regular keyboard. Applications that use the Tab key to move between fields will benefit from the location and ease of use of the ZTab key, which was specifically designed for data intensive applications, especially for users who are keying in primarily numeric data. The ZTab key is extra large to allow the use of fingers and thumb to operate the ZTab key with varying positions of the hand.
