Efficient navigation of callback functions

Do kernel developers use any tools/plugin to quickly navigate through callback functions? I use Vim & Source insight to navigate kernel source tree but these tools are not good at callbacks/function pointers. Every time i have to grep for the assignment of function pointer and then search for the function (instead of using tags). Is there a better way? This question is not linux kernel specific but since linux kernel heavily uses callback functions i thought i can get some pointers. Thanks, Sailesh
