1. A chordic keyboard comprising:
- at least five chordic data entry locations, each corresponding to a one of the five fingers of the human hand; and
first correlation means for correlating a set of chordic data entry location engagement combinations to a first set of letters in accordance with a first code, said first code being characterized in that available chordic data entry location engagement combinations are arranged in a plurality of groups, the engagement combinations in each group having a predetermined relationship among their fingering patterns, each group being matched with letters forming a recognizable combination of letters, whereby said fingering patterns are readily memorizable and wherein said first code is additionally characterized in that chordic data entry location engagements having relatively easy motoric transitions therebetween are matched to letters statistically occuring adjacent each other with relatively high frequency.
