When is the CONTROL key not a control key?

[Richmond]

So; reading the LC documentation (for the first time in ages) I 
discovered that ctrlKey() returns the state
of the Control key on non-Mac computers (such as those running Windows 
and Linux), but the state
of the Command key on Macs.

Jolly nice.

How do I find out the state of the key marked 'ctrl' on my Mac keyboard 
that is connected to a Mac?

I guess I just want too much.
