Just double checked — neither iTerm not Terminal allow the Ctrl modifier for clipboard operations. In fact, terminal applications are _precisely_ the applications I use to argue that Cmd-X/C/V is overall nicer, as they don't interfere with the usual meaning of the Ctrl modifier as a way to produce control characters (which are especially useful in the context of a terminal)
Hm, perhaps you're right, it was some time ago I used a Mac, sorry for the confusion. There was something with Emacs also which was weird on the mac with modifier keys but I don't exactly remember what.
