Abstract

A technique is described whereby the IBM Personal Computer full function 83-key keyboard may be reduced in size to a 62-key keyboard without sacrificing the full function capabilities of the larger keyboard. The 83-key keyboard, as shown in Fig. 1, can be reduced in size as shown in Fig. 2. To accomplish the reduction in size, 21 keys are eliminated by combining functions and utilizing depression of two keys to obtain the full function capabilities. To accomplish this, a new "Fn" key is created which, when depressed simultaneously with a numeric key, will produce the same function as the Function Keys in Fig. 1, except that the "0" + F keys take the place of the F10 key. The keys that have been eliminated and the equivalent function provided in the new Fig.

Mapping the Personal Computer 83-Key Keyboard to a 62-Key Keyboard

A technique is described whereby the IBM Personal Computer full function 83-key keyboard may be reduced in size to a 62-key keyboard without sacrificing the full function capabilities of the larger keyboard. The 83-key keyboard, as shown in Fig. 1, can be reduced in size as shown in Fig. 2. To accomplish the reduction in size, 21 keys are eliminated by combining functions and utilizing depression of two keys to obtain the full function capabilities. To accomplish this, a new "Fn" key is created which, when depressed simultaneously with a numeric key, will produce the same function as the Function Keys in Fig. 1, except that the "0" + F keys take the place of the F10 key. The keys that have been eliminated and the equivalent function provided in the new Fig. 2 keyboard are as follows: KEYS ELIMINATED EQUIVALENT KEYSTROKES F1 - F10 Fn + numeric keys 1-10
