I wasn't trying to claim that "point and click" is superior. It was just my question whether such tools are available. I'm also more of a command line monkey, but it gets old at times to do the same thing I was doing 10 years ago over and over.

My point is that much more intelligent, useful and efficient queries could be possible by making use of the fact that code is a data structure, and not just text. Various things could be inferred automatically, which would be especially handy in legacy C source code where it's really hard to make head or tail of (I see a lot of that in my job).

It should be able to answer questions like "where does this value come from", "how is it computed" and show a tree/chain of statements. Or "where is this structure accessed" ... and so on.

As clang makes these things easier, I hope there will be a new resurgence in intelligent code comprehension tools. Those don't necessarily have to be point and click, but could have different UIs...
