USB King Keyboard
QWERTY & English FUO (frequency of use) Layouts
A small size alternative keyboard that plugs directly into a computer. No special interface is required. Membrane keys are less than .5" (1.3 cm) square and are closely spaced for easy access. The keyboard surface is very sensitive.
A Frequency of Use keyboard is designed with the most frequently
used letters placed toward the center of the keyboard. This may help to
expedite text entry and minimize fatigue.
