Abstract: A portable information handling system keyboard includes plural keys that each have a programmable variable-feel response to an end user experience with key interactions in real time. In one example embodiment, a magnetic-rheological fluid is disposed in a chamber of the key to pass through openings formed in a piston that moves downward with a keypress and upward in response to a biasing mechanism, such as a spring disposed in the chamber. Current applied to a coil around the chamber creates a magnetic field that varies the viscosity of the fluid so that key compression and range of motion associated with an input as well as key movement to a raised position are programmable to adjust based upon a sensed key position and movement.
