Mouse left button isDown: Key.isDown(1) Doesn't work on Macs

Some of you may or may not be aware that the following code can detect that the mouse button is down. (Something that’s oddly missing from the Flash API.)


if (Key.isDown(1)){
 trace("left mouse button down");
}
if (Key.isDown(2)){
 trace("right mouse button down");
}

[COLOR=red]However, this has been reported to not work on Mac computers![/COLOR]
I do not recommend using / relying on the above code.

The question is: Is anyone aware if there exists a Key Code for the Mac mouse button?
I do not own a Mac and do have close contacts to people with one, so I cannot test this for myself.
