A multimedia keyboard includes a general text key zone and a special function key zone. The latter is further divided into eight major function zones, including a function key converting zone, connected to I/O ports of a microprocessor included in an internal circuit configuration of the keyboard. The keyboard uses a seventh class code that defines E2 as a leading code and an intercept scan code program to enable use of keys in the function key converting zone to select whether to decode the leading code E2 or not, so that a connected computer may determine whether a keyboard code is a conventional or a non-conventional identification part. Whereby the keyboard provides shortcut key functions without the need of any special driver, and may be expanded to provide new function keys when the computer selects to identify the non-conventional identification part.
