while I don't disagree that people should perform a search on this forum or online in general first, searching is only helpful when you know what to call the item you're searching for. in this case, it relies on the user knowing that the toolbar currently attached to the main tool bar is called the "Quick Access" tool bar. if you don't know this, you don't know what to search for.
Please search the forum before asking.
