Your question is unclear. Because we're talking about a NSOutlineView, "selected" means what you're calling "highlighted" below. It's better not to use "selected" to refer to the on/off state of your button cells. Let's call that "active".

If you're trying to maintain a NSArray of "active" instruments, the correct place would be outlineView:setObjectValue:forTableColumn:byItem:, since that's the point at which you get told of the change of state.

I'm not sure what the NSIndexSet is for. Do you mean "selected" or "active"?
