A keyboard arrangement that assigns alphanumeric and special character symbols to keys based upon the shapes of the symbols in order to facilitate learning to type. Attribute classes are defined according to the number, position, direction, or contours of the line segments that comprise the symbols. As an aid to memorization of a keyboard arrangement, symbols are assigned to keys such that a substantial number of keys in a column of keys belong to the same attribute class. To convert any prior art or other kind of electronic keyboard to a keyboard arrangement within the scope of the invention, hardware and/or software components are provided that reassign the keys so that substantially all keys within the same column will correspond to symbols within the same attribute class. The scope of the invention includes keyboard arrangements that dispense with keys entirely and substitute therefor devices that are each capable of coding for as many symbols as two or more conventional keyboard keys; each of the devices is made to correspond to symbols within the same attribute class.
