A numeric or character vector
This function provides a mapping between the human-readable
javascript key names and their corresponding numeric code
values. If both input arguments are NULL, it returns a named
numeric vector whose values correspond to the key codes and whose names
correspond to the key names. If key is specified the return value
is a vector with the corresponding numeric codes; whereas if code
is specified the output is a character vector containing the corresponding
key names. If neither argument is NULL the function throws an error.
