Huh? how come? in other windows apps it is ctl-click.
well, i just checked and Word does ctl-click for copy, wordpad does click drag ctl for copy!
and, trying it in 7.1 i see that BOTH ways are supported.
i can see where click drag ctl would be nice, if you start to drag and then decide o i should have ctl-clicked you can correct your mistake easier.
i don't remember seeing this in the list of new things for 7.1 though.
