A key constructing method for a keyboard has M scan lines * N return lines. The electrical interconnects of the M scan lines*N return lines can generate numerical electrical contacts of A1 to AM*N, while the numerical electrical contacts of {A1 to AM*N}are the electrical contact set {A}. This key constructing method for the keyboard comprises the steps of: selecting at least one or more electrical contacts from the electrical contact set {A} to create an electrical contact set {B}; creating the electrical contact set {C}, while the electrical contact set {C}=the electrical contact set {A}−the electrical contact set {B}; combining at least one electrical contact from the electrical contact set {C} with one of the electrical contacts from the electrical contact set {B} to generate an expanded key; and, or, after the expanded key is pressed, outputting at least one or more key codes by the keyboard, wherein the key codes are used to recognize the expanded key.
A key constructing method for a keyboard having M scan lines and N return lines, wherein M scan lines*N return lines generate electrical contacts of A1, A2, A3, . . . to AM*N, and said electrical contacts of {A1, A2, A3, . . . , AM*N} is an electrical contact set {A}, comprising the steps of:
A key constructing method for a keyboard having M scan lines and N return lines, wherein M scan lines and N return lines can generate scan/return lines of A1, A2, A3, . . . to AM+N, and said scan/return lines of {A1, A2, A3, . . . , AM+N} are a scan/return line set {A}, comprising the steps of:
