4. The data input apparatus of claim 3 wherein said circuitry associated with said keyboard base includes identifier switches engaged by said keyframe to determine said arrangement of said plurality of keys.

5. The data input apparatus of claim 1 wherein actuation of said identifier switches generates a signal unique to said keyframe.

6. The data input apparatus of claim 4 wherein said keyframe includes at least one extending member for contacting said identifier switches upon mating of said keyframe to said keyboard base.

7. The data input apparatus of claim 1 wherein said keyframe enables single keystroke entry of one of business symbols, multimedia symbols, mathematical symbols, and manufacturing symbols.

8. Apparatus for inputting object-orientated data to a computer, comprising:

a plurality of keys;

a keyboard base;

a keyframe connectable to said keyboard base and identifiable by the computer, and wherein said keyframe is configured to accommodate said plurality of keys; and

,

circuitry in said keyboard base having switches actuateable by said plurality of keys and said keyframe for generating and transmitting data specifying an arrangement of said plurality of keys and a key character to the computer upon actuation of one of said plurality of keys.

9. The apparatus of claim 8 wherein said plurality of keys are integrated into said keyframe.

10. The apparatus of claim 8 wherein one or more of said plurality of keys are symbol keys, each of said symbol keys configured to generate a symbol signal representative of a respective symbol key to a CPU upon single keystroke actuation of said respective symbol key.

11. The apparatus of claim 8 wherein one or more of said plurality of keys are function keys, each of said function keys being configured to generate a signal representative of a respective function key to a CPU upon single keystroke actuation of said respective function key.

12. The apparatus of claim 10 wherein said circuitry comprises a plurality of interconnected switches having a switch for each of said symbol keys.

13. The apparatus of claim 8 wherein said circuitry includes one or more opto-electronic switches for identifying said keyframe.

14. The apparatus of claim 8 wherein said keyframe includes one or more extending members for engaging one or more of said switches of said circuitry.

15. The apparatus of claim 14 wherein said arrangement of said plurality of keys is identifiable by a number of said one or more extending members on said keyframe.

16. An apparatus for use with a keyboard base of a computer, the keyboard base having a matrix of switches engageable with a plurality of keys, the apparatus comprising:

a keyframe configured to accommodate the plurality of keys; and

,

wherein said keyframe includes a means for transmitting one or more keyframe identifier signals to the computer upon a mating of said keyframe to the keyboard base.

17. The apparatus of claim 16 wherein said means for transmitting one or more keyframe identifier signals to the computer comprises one or more extending members connected to said keyframe and configured to engage one or more switches of the matrix of switches upon said mating of said keyframe to the keyboard base.

18. The apparatus of claim 16 wherein said keyframe includes actuating members for engaging the plurality of keys.

19. The apparatus of claim 16 wherein said keyframe enables single keystroke entry of one of business symbols, multimedia symbols, mathematical symbols, and manufacturing symbols.

20. A computer system comprising:

a CPU;

a display unit connected to said CPU for displaying symbols; and

,

a keyboard having circuitry associated therewith to communicate with said CPU, said keyboard further comprising;

a plurality of keys;

a keyboard base having one or more switches actuatable by said plurality of keys; and

,

a keyframe mateable with said keyboard base, wherein a mating of said keyframe to said keyboard base causes one or more signals to be transmitted to said CPU identifying an arrangement of said plurality of keys on said keyframe.

21. The computer system of claim 20 wherein said keyframe includes actuating members for engaging said plurality of keys.

22. The computer system of claim 20 wherein said keyframe includes one or more opto-electronic sensor switches configured for transmitting optical energy from a transmitter to a receiver of each of said opto-electronic sensor switches.

23. The computer system of claim 22 wherein at least one elongated member is connected to said keyframe and prevents passage of said optical energy between said transmitter and said receiver upon a mating of said keyframe to said keyboard base.

28. The apparatus of claim 20 wherein said keyframe includes one or more removeable key set portions.

29. The apparatus of claim 28 wherein said removeable key set portions have one or more elongated members associated therewith.

24. A data input apparatus for a data processing device, comprising:
