Open the Preferences using the button in the Enviroment section on the Home tab of the Toolstrip. In the MATLAB section of the preferences expand Keyboard and click on the Shortcuts sub-item. Search for action name "Comment" to see the shortcut that is currently enabled to perform that action. If Ctrl-R is not listed, I'm guessing you're using either Emacs or Mac shortcuts. You could customize that one action's shortcut or change the whole set to "Windows Default Set".

Did you ever figure this out? I am having the same issue. Ctrl + R won't register in the keyboard mapping preferences screen.

I wonder if some other application is intercepting the Ctrl+R combination before it reaches MATLAB. For example you couldn't set a keyboard shortcut to Ctrl+Alt+Delete in MATLAB because Windows says "No, that's for me." and takes care of the combination before MATLAB can learn that those keys were pressed.
Maybe some sort of screen capture program? Unfortunately without knowing what applications you have, testing this hypothesis could be a challenge. Does anything happen on the computer, even outside MATLAB, when you press Ctrl+R?
