These 36 keys keyboards enable all major functions of a large MF keyboard in a small outline. Function keys F1 to F16 and complete upper and lower case alphabet are available. Distinct and easy recognition of the different functions due to three different legend colors corresponding with the mode-keys: black for UNSHIFT; red for SHIFT and green for ALPHA mode which is a toggle function indicated by a separate green LED. These handheld keyboards are ideal for applications requiring only a limited number of key functions with fast and comfortable key access.
