That is correct.

Can you explain your confusion a bit more - I'm not entirely sure what
you're asking, and it's very hard to answer questions when you don't
know the actual question. 

Also, it's much better if you explain a little bit about what you're
trying to achieve (I've previously used the example of someone having a
puncture, going to ask the mechanic how to loosen a wheel-nut, then
going to ask how to jack up the car, then asking how to tighten the
wheel-nut, when the actual problem is a punctured tyre, and the "right"
question to ask a mechanic is "How do I replace my punctured tyre with
the spare wheel?"). 

Asking the overall question you're trying to solve will give you a more
complete answer to what you're trying to do, rather than a detailed
answer on the point where you're at (and that may actually not help your
overall problem at all).
