Eclipse CDT (Juno) does it even better. Just hover a mouse over any function call and you can see the body of that function in a scrollable tooltip. You don't need to jump back and forth - you simply follow the code logic and see what the called function does in a tooltip window. This is a huge productivity boost for me and I haven't seen any other IDE doing it.
One other thing no other tool does (AFAIK) is that you can get a "call hierarchy" for a function or any variable and it's laid out as a tree and you can expand each node to trace the calls. This makes understanding the code and refactoring faster by an order of magnitude.
I have avoided Eclipse for years because of cpu/memory usage, but ever since I got a computer with Intel i7 CPU and 16GB of RAM, I have completely switched to Eclipse because it makes me so much more productive than any other environment I tried.
