Not exactly an > appealing prefix. The same could be said for C-o or M-o. And if you care about non-QWERTY layouts, C-z on a German QWERTZ keyboard isn't much better. (Also I wonder, aren't Shift, Ctrl, and Alt keys meant to be used crosswise, i.e., left key for the right half of the keyboard, and vice versa? For example, how do you type C-b or C-t?)
