VI has a feature like CBs "Find Implementation", CTRL-] jumps to the tag of the function under the cursor. VI compliments this with an unwind feature - pressing CTRL-T returns to previous point from which you CTRL-].
This is implemented as a stack, which makes tracing non-running code incredibly easy: You can descend down thru a dozen calls and then unwind - like returning up the stack in the debugger.
Is there a plugin for CB that does something like this?
