A keyboard allowing typists to use approximate QWERTY finger movements on a more compact, collapsible, and portable keyboard. The keyboard size is made more compact by using thin capacitance-responsive surfaces as key switches for the rows above and below the home row. The bottom, space-bar row is also touch-sensitive and is placed on the side of the keyboard facing the typist The capacitance-responsive surface for the row of keys switches above the home row has a convex profile, and the capacitance-responsive surface for the row of keys switches below the home row has a concave profile, such that the keyboard can fold compactly upon itself. The home row retains depressible key switches in order to provide standard rest positions for the fingers. Characters and commands assigned to the rows above and below the home row are engaged by sliding the fingers over the capacitance-responsive surfaces adjacent to the home row.
