It's not bad if you have a keyboard (e.g. topre) with control in the caps-lock position (or remap it, which I usually do).

And I also agree that the Lisa/Mac-style command-[zxcv] works really well (particularly if you use a mouse with your right hand.)

MacOS has no problem with both control-c (break) and command-c (copy) - why isn't this common in Linux as well (at least for keyboards with a command or windows key, which seems to be many, many keyboards.)
