    the keyboard buffer by all the possible keystrokes and two-keystroke
    combinations on the 83/84-key and 101/102-key keyboards. These are the
    values returned (as strings) by the INKEY$ function.

         [1]    The 83-key and 84-key keyboards are the original PC
                keyboard and the original-layout AT keyboard,
                respectively.

         [2]    The 101/102-key keyboard is the current IBM standard
                ("Enhanced") keyboard.

         [3]    In the United States, the 101/102-key keyboard is shipped
                with 101 keys. Overseas versions have an additional key
                sandwiched between the left Shift key and the Z key. This
                additional key is identified by IBM (and in this table) as
                "Key 45."

        [**]    Keys and key combinations marked ** are used by the ROM
                BIOS but do not put values into the keyboard buffer.

        [--]    Keys and key combinations marked -- are ignored by the ROM
                BIOS.
