Abstract: A keyboard arrangement with a pair of angularly disposed, spaced apart groups of character keys dedicated for operating use respectively by the left hand and the right hand of a user. A space bar key is operable by either thumb of the user and bridges between the two groups of character keys. The rows of keys in each group are staggered, and each key bears character indicia disposed at an angle to the transverse direction of its group of keys.
