That may be so, but it does not change the fact about the misbehaving: invoking the search by right-click on a term in a comment does nothing whereas doing the same on a non comment term does a search as expected ...
That a term inside a comment falls out of the category of source symbol does not seem quite right. Many times one just comments-out a piece of code to test an alternative, the commented line still "stays" code in that sense ...
Well, just my opinion, and I'm definitively not a pro ...
Maybe the difference between code searching and literal searching just does not come out clearly enough through the names of the commands or its locations ...
