Sure. I've got a window. (Actually, there are several windows, but

Is there a deep reason that there's not an IB action for this?

That's perfect. Thanks!
It's also possible to set the tag in IB (it's on the Attributes
Inspector palette, in the "control" tab). Since I'm not creating any
dynamically, I can do that.
I've got a sub-class of NSTableView. I have windows that have more
than one instance of this TableView in them, which need to behave
slightly differently, based on which one they are. (There are three

NSArray allows duplicate items; NSSet does not. What do you

I can roll my own, of course, but there are so many builtins, I'd have
