1. An apparatus comprising:

  • a keyboard for touch typing having a home row of locations for each of 8 fingers to rest concurrently, and providing single stroke access to every letter of a full alphabet, the keyboard having a plurality of mechanical keys, each key having a surface area for actuation by a finger, and each key maps to at least three functions and each key can move at least 1.0 mm responsive to sufficient pressure by the finger, wherein the key surface remains substantially parallel to a rest plane while the key moves to access each letter associated with the key, and wherein the rest plane is a plane defined by the key surface in the absence of an actuation force;

    wherein each function is associated with a zone occupying an area on the surface of the key; and

    wherein a key function selection is made by interpreting the location of the finger relative to the zones during actuation; and

    wherein a zone of actuation of the finger may overlap with multiple zones and a single function is selected by at least in part interpreting the pattern of finger overlap with the multiple zones.
