A flexible or roll-up electronic keyboard is provided for use with electronic devices. The keyboard is formed with a plurality of section of flexible plastic materials and embodies a dual-walled bottom which includes a network of support members which can be inflatable to provide a rigidity to the structure of the keyboard sufficient to prevent false signals. At least one separately inflatable accordion-pleated wedge means is also provided to enable variable adjustment of the plane or planes of the keyboard relative to the hands of its operator, sufficient to reduce the risk of nerve disorders such as carpal tunnel syndrome in the operator.
