My point was that if there's a CTRL key on each side of the keyboard, then anything involving a ctrl+something is one-handed-able.

Whether it's good typing practice to use one hand for both the ctrl and the C, say, in a ctrl-c construct - I can't say.

I know that I rarely if ever use the right-hand control or alt keys (on a standard US-mode PC keyboard that has alt and control keys on both sides). I suspect this is poor form.
