5. The keyboard core structure of claim 1 with the keys in the transverse rows Third Nearest, Second Nearest and Nearest the operator being assigned the following characters in sequence from left to right: Third Nearest Row: Q W E R T Y U I O and P Second Nearest Row: A S D F G H J K L and ; Nearest Row: Z X C V B N M , . and ? which key arrangement is known as the Standard or Qwerty arrangement.

6. The keyboard core structure of claim 1 with the keys in the transverse rows Third Nearest, Second Nearest and Nearest the operator being assigned the following characters in sequence from left to right: Third Nearest Row: ' , . P Y F G C R and L Second Nearest Row: A O E U I D H T N and S Nearest Row: ; Q J K X B M W V and Z which key arrangement is known as the Alternate Standard or Dvorak arrangement.

7. A method of operating keyboards having at least forty keys with the fingers of both hands by touch without looking at said keyboard to operate said forty keys, the method comprising the steps of: providing a keyboard with a Core Structure arranged as shown in the drawing; the operator positioning the keyboard in relation to his/her body or positioning his/her body in relation to the keyboard, so that the space between the Fifth and Sixth columns of keys in said Core Structure is in line with the mid-line of the operator's body, said positioning being done by visually aligning said space with the mid-line of the body or by tactilly aligning said space with the mid-line of the body; the operator maintaining said alignment of said space between the Fifth and Sixth columns of keys in said Core Structure with the mid-line of the body during operation of the keyboard by visually or tactilly checking the location of said space in relation to the mid-line of the body from time to time and moving the keyboard or the body to restore alignment of said space between said Fifth and Sixth columns of keys with the mid-line of the operator's body; designating an Operating Finger to operate each of said forty keys in said Core Structure, which Operating Finger designations are: Little Finger of the Left Hand for the First Key in each row, Third Finger of the Left Hand for the Second Key in each row, Middle Finger of the Left Hand for the Third Key in each row, Index Finger of the Left Hand for the Fourth and Fifth Key in each row, Index Finger of the Right Hand for the Sixth and Seventh Key in each row, Middle Finger of the Right Hand for the Eighth Key in each, row, Third Finger of the Right Hand for the Ninth Key in each row, Little Finger of the Right Hand for the Tenth Key in each row; assigning an Operating Position or Home Position to the fingertip of the Little, Third, Middle, and Index finger of each hand, which Operating Position for each of said fingertips is on or over a specified key in the Second Nearest row, and when the keyboard is viewed from left to right by the operator the Operating Position for each fingertip is: Little Finger of Left Hand on or over First Key, Third Finger of Left Hand on or over Second Key, Middle Finger of Left Hand on or over Third Key, Index Finger of Left Hand on or over Fourth Key, Index Finger of Right Hand on or over Seventh Key, Middle Finger of Right Hand on or over Eighth Key, Third Finger of Right Hand on or over Ninth Key, Little Finger of Right Hand on or over Tenth Key; when the keyboard is being operated, each of said eight fingertips rests lightly on or over its Operating Position and operates the keys for which it is the designated Operating Finger by moving the fingertip from its Operating Position to the key to be operated, and after having operated said key, returning the fingertip of the Operating Finger to its Operating Position; the operator positioning the fingertips of his/her Little, Third Middle and Index fingers of his/her Left Hand in said Operating Positions on or over the First, Second, Third and Fourth keys in the Second Nearest Row of said Core Structure by using the Left Thumb to tactilly sense the right side of the Fifth Key in the Nearest Row of said Core Structure, and the operator maintaining the fingertips of said four fingers of the Left Hand on or over said four keys in said Second Nearest Row, by using the Left Thumb to tactilly sense the right side of said Fifth key in said Nearest Row from time to time during operation of the keyboard and repositioning the fingertips of said four fingers of the Left Hand on or over said First, Second, Third, and Fourth keys in said Second Nearest Row of said Core Structure; the operator positioning the fingertips of the Little, Third, Middle and Index fingers of the Right Hand in said Operating Positions on or over the Tenth, Ninth, Eighth, and Seventh keys in the Second Nearest Row of said Core Structure by using the Right Thumb to tactilly sense the left side of the Sixth key in the Nearest Row of said Core Structure, and the operator maintaining the fingertips of said four fingers of the Right Hand on or over said four keys in said Second Nearest Row, by using the Right Thumb to tactilly sense the left side of said Sixth key in said Nearest Row from time to time during operation of the keyboard and repositioning the fingertips of said four fingers of the Right Hand on or over said Tenth, Ninth, Eighth and Seventh keys in said Second Nearest Row of said Core Structure; the operator operating the First, Second, Third, Fourth, Seventh, Eighth, Ninth, and Tenth keys of the Second Nearest Row by tapping the finger strike surface of each of said eight keys with the fingertip of the Operating Finger for the key to be operated; the operator operating the ten keys of the Third Nearest and Fourth Nearest Rows by extending the Operating Finger for the key to be operated from the Operating Position for that Operating Finger to the key to be operated and tapping the finger strike surface of the key to be operated with the fingertip of the Operating Finger, and then returning the fingertip of the Operating Finger to its Operating Position; the operator operating the ten keys of the Nearest Row by flexing or curling the Operating Finger for the key to be operated from the Operating Position for that Operating Finger in the Second Nearest Row to the key to be operated and tapping the finger strike surface of the key to be operated with the fingertip of the Operating Finger, and then returning said fingertip of said Operating Finger to its Operating Position in said Second Nearest Row; the operator operating all keys in all rows of said Core Structure, without any Operating Finger physically contacting, brushing, rubbing, grazing, touching, hurdling over, going under or overlapping an adjacent finger, and without any other finger being moved, displaced, pulled, pushed, or raised from its Operating Position, and without lateral or rotation movement of either hand, and without wrist deviation movement of either wrist, and without rotational movement of either forearm, and without lateral movement of either elbow.
