Well, the problem is that my fingers are trained to hit C-c C-c when I
get into a syntax error continuation loop in R or when I enter a
computation that I realize is wrong and going to take awhile.

So I need to find a way to make C-c C-c do what I want :-)

For now, I realized that I can remap C-c C-c to something harmless and
at least prevent silly mistakes.

What is '~B'?

My fingers are crossed. ;-)
