Subject: return up two levels?

Didn't I read somewhere that one can return from a function 'up two
levels'? i.e. that if function1 calls function2, that function2 can
return both itself and function1? I have a helper function that might
want to return to the calling function, or might want to return right
back to the shell. Of course I can do this with with return value tests
within the calling function, but it would be nice if the helper function
could handle it internally. Is it possible? 'exit' kills the shell
itself, so it's too aggressive.
