Touch type keyboard using temporal evatuation of timestamps to modify key functions

A touch type keyboard comprising:

• an array of tactile keys defining a home row of locations that allow each of eight fingers to rest concurrently in the course of touch-typing, and providing single stroke access to every letter of a full alphabet through unique locations on the array;
• and
• a controller configured to apply a timestamp for each of a plurality of key actuation events at the different key locations,
• wherein the controller is configured to identify when at least one of the home row locations and a second home row location are actuated concurrently as a signal to switch a function of a third location in the array to a different keyboard function;
• and
• wherein the identification is based at least in part, on a temporal relation of the timestamps;
• and wherein the controller is configured to evaluate the temporal relation after the events have occurred and before reporting the events to the host.
