accessing full history in Safari

Hi all,
I've had this problem for several years now, and can't figure out how to solve it. I was told fairly early on that holding down the forward or back buttons was the way to bring up history when in Safari, but that seems to only partially work. When I do that, it only pulls up what I've accessed in that particular tab. How do I tell it to show me everything I've ever accessed since I last reset my history?
