Note: The following #defines map "key" calls on AERecords into "param" calls on
AppleEvents. Although no errors are currently returned if AERecords are
passed to "param" calls and AppleEvents to "key" calls, the behavior of
this type of API-mixing is not explicitly documented in Inside Macintosh.
It just happens that the "key" calls have the same functionality as their
"param" counterparts. Since none of the "key" calls are currently available
in the PowerPC IntefaceLib, the #defines exploit the fact that "key" and
"param" routines can be used interchangeably, and makes sure that every
invokation of a "key" API becomes an invokation of a "param" API.
