That's exactly what I was looking for! 
And regarding Stefan's observation that the prescription on the Wiki for a 
plist item for this Qt attribute doesn't work: yes, without patching Qt I can 
currently only see application-specific mechanisms for setting this "dontSwap" 
So if I put Pavel's suggestion in, would my checkbox patch be acceptable? As I 
said, I'd be OK without GUI, but I don't really think it will hurt anyone to 
have it in there, with the default being not to change the key mapping.
