NAME
  Declaring User-Defined Keys

SYNOPSIS
  KEY n%, CHR$(keyboardflag%) + CHR$(scancode%)

      _ n%               A value in the range 15 through 25 that identifies
                         the key.
      _ keyboardflag%    One of the following values, or a sum of values,
                         specifying whether the user-defined key is used in
                         combination with the Shift, Ctrl, Alt, NumLock, or
                         Caps Lock keys, or with extended keys:

                         Value            Key
                         -------------    -----------------------------------
                         0                No keyboard flag
                         1 through 3      Either Shift key
                         4                Ctrl key
                         8                Alt key
                         32               NumLock key
                         64               Caps Lock key
                         128              Extended keys on a 101-key keyboard

                         To specify multiple shift states, add the values
                         together. For example, a value of 12 specifies that
                         the user-defined key is used in combination with
                         the Ctrl and Alt keys.

      _ scancode%        The scan code for the key being declared.
                         See Keyboard Scan Codes.
