I suspect this is keyboard dependent.  I do C-\ all the time with  
both right and left control, and I press Ctrl-AltGr-+ (hold down all  
three keys at the same time, which I press first or last does not  
matter) on my swedish keyboard (and add Alt to that, i.e. Alt-Ctrl- 
AltGr-+, gets me M-C-\, but it is not very ergonomic).  The trick  
above does not work for me at all.
