What does the $("someId") operator do? I've never seen this before and I can't seem to find anything out about it.

in php? It's a 'variable variable'.
It should probably read ${"some str which might be stored in another variable"}.
So you have
$whatever = "Hello";
$shu = "whatever";
print ${$shu};
will output "Hello".

All clear?

I believe the general name for that sort of thing is "indirection."

It would certainly help if you let us in on what language you are referring to, and where/how you came across this...

Oh I figured it out...

Oh and it was in Javascript.

It's actually part of the DWR (Direct Web Remoting) API, and I think its a function to return an element based on your browser type. It's quite odd.
