to hold it there.

That's just it: If there were no trim at all, the elevator wouldn't
be there. It would be in its neutral position. Of course you can
_push_ it there, but with trim set, it goes there and stays there
without being pushed (by you).

In this case, you really need to listen to what Thomas and others are
saying. There is no neutral position. There is just a natural
position for a certain flight regime.

Therefore, if you are hand-flying, and you move the trim, the airplane
will react. The pilot will notice this (it's impossible not to).

I'm trying to think of a relevant example using a car or roller coaster
or other easy to understand situation, but I don't have enough coffee
in me yet :-) Perhaps someone else can some up with something.
