You can put whatever data you want/need in the pasteboard item. Even multiple
independent things. A handy trick is often to add a private type per item. This
custom type can be as simple as the index of the item in the source list.
So obviously I need to use tableView:pasteboardWriterForRow:.
NSScrollView does various checks to see if the App is trying to put placards in
the scroller area. If NSScrollView thinks there are placards, then it reverts
back to legacy scrollers for compatibility. Some apps have been known to do
this via a sibling view instead of a subview. This is why it
There is probably a subview that is intercepting the event. You subclass should

The target of the menus should be nil and you need to set the action to what
standard controls expect them to be. Namely:

Hi David,
As you switch views due to tab switching, the newly added view sets up it's
next responder based on the view hierarchy. The new view coming in doesn't know
anything about your view controller and simply wires up it's newt responder as
it's parent view.
