Find uncalled functions (dead code) in ReSharper c++

I see a lot of explanations on how to find dead code in C# and .NET, but not in c++. I have selected ReSharper > Code Inspection > Settings > Enable solution-wide analysis. Most instructions I've seen say to then group by Issue Type and look under undefined... but I'm not seeing undefined functions there. FWIW, I just started using ReSharper c++ (totally impressed!), so I'd appreciate answers targeted to a newb. Thanks!
