I think it might be fairly dangerous if you have an application open 
that contains work you have not saved.

I also found that the opposite effect is achieved with ctrl-\. Kind of 
made sense that slash and backslash were opposites.

Also discovered with an analogous strategy. I got no effect with 
ctrl-<any of the middle tier of keys>
