I created the key on another computer, so the secret key was never on
this machine in the first place.

Yeah, another 8 characters would have made the line wrap around. :)

Yes, just like in my example, you would usually specify the ID of one of
your own keys.

So say I've certified your key with my 215236DA. That key is not on this
machine, but I'd like my gnupg to consider your email signatures valid.
What I'm telling gnupg is that 215236DA is my own key, so any other key
that is certified by 215236DA must be valid (presumably because I
personally checked this before certifying).

trusted-key is really there for the above scenario -- it is my key, but
it isn't on this computer, so gnupg can't know unless I tell it. There's
basically not much more to it.*

* Now, that's a meaningful sentence right there. "Ignoring anything else
there is to it, there's not much more to it."

No situation is so dire that panic cannot make it worse.
