Not true, the Mac OS (Classic and X) and Windows can tell the 
difference between the left and right keys (shift, control, alt/option 
and command)

   From his FAQ:

"Is it possible to distinguish between the right and left Option and 
Command keys?
Yes, it is possible (anything's possible) but, in short, the answer is 
no. The calls that uControl intercepts are at too high a level for it 
to distinguish between right and left keys. It might be possible to 
drag uControl down into a lower subsystem, but I don't envision myself 
doing it. Alex Harper, though, he's one you should watch."
