Abstract

In a method of transmitting key codes of hot keys from a number pad, the number pad includes at least one hot key and several key code sets corresponding to the hot keys. Each key code set has key codes formed and edited according to a first key code conversion table and a predetermined sequence. When a hot key is pressed, the number pad transmits all key codes to an electronic device according to the predetermined transmitting sequence. The electronic device reads each key code by the first encoding format. The key codes are converted into characters corresponding to the first key code conversion table according to the first key code conversion table, and also into characters corresponding to the second key code conversion table according to the second key code conversion table in a second encoding format, such that the electronic device produces expected conversion results.
