[R-SIG-Mac] Shortcut to apply comment character to a block of code in editor?

[Carl Witthoft]

Hi,
Someone claimed in this StackOverflow thread 
http://stackoverflow.com/questions/9107695/r-comment-out-block-of-code 
that the sequence "CMD-OPT-`"  would comment the selected block.  What 
it does, on my machine, is to place the "`" at the start and end of the 
selection, which of course just makes a mess.

So-- is there actually a  keystroke to apply "#" to all selected rows in 
the editor?  And while I'm at it,  does "CMD-OPT-`" have an intended 
use, or is it something "leftover" in the R.app editor code?

Many thanks
Carl
