Two ways:
- you can use the list view instead of the graphical view. On the right
side of the "Instances" pane there are two tiny icons, one with four
squares and one with horizontal lines. Click the horizontal lines.
- you can access it in the graphical view of IB if you try to make a
connection on the very edge of the web-view area. Not sure why it works
that way, it just does.

But I mean, how do I access it in IB? All I can select is the WebView.

Well, typically you'd make an outlet in IB, like with any other view.

Aha, okay. But how do I access the NSScrollView?

The web view is embedded inside an NSScrollView, which is in charge
of the scrollers. You can hide them that way.

I have a method that takes a screenshot of a WebView, but I don't
want there to be scroll bars in the screenshot. I don't see a way
to set the WebView to not have scroll bars, without perhaps
subclassing it, so I thought the easiest way would be to determine
if scroll bars show up in the screenshot, and if they do, cut them
out.
I'm rather new to Cocoa, so I might be doing this wrong. Is there
a better way to do this?
