The invention is directed to an improvement or enhancement of a keyboard. Particularly, the keys of a keyboard are enhanced or modified to improve or instill a tactile sensation to a person doing the typing. In this respect, certain of the keys are modified by adding tactile edges to the keys. typing school and instructors and instructions for the beginners instruct the learners to place their fingers in the middle row of the lettered keyboard. Instructions further advise to divide this middle row into two groups, one for the left hand and one for the right hand. Both groups involve the four fingers of each group excluding the thumb. The four fingers of the left hand will be placed over the letters A through F and the fingers of the right hand are placed over the letters J, K, L including the semi colon. The outside edges of the key letter A of the left hand and on the semicolon key of the right hand have outside raised edges placed thereon. This way the four fingers of the left hand and the four fingers of the right are sort of cradled between the raised edges and gives the typist a tactile sensation indicating where exactly the fingers are placed on the keyboard which enhances the speed and the accuracy of the person doing the typing.
