A changeable keyboard arrangement includes a database established in the memory of an electronic device, with a minimum of one or more keyboard layout code-page tables stored in the database such that the user can change to a different keyboard layout on the electronic device, and after selecting the key configuration of the keyboard to be changed from a keyboard layout set-up menu, the CPU of the electronic device reads numbers from the key code-page table stored beforehand in the memory; as such, when the user changes a keyboard layout and presses various keys, the CPU searches for the corresponding numbers in the code-page tables based on the first signal issued by the contacts of the keys within a unit interval and then executes the relevant processing.
