How to Navigate and Move Tabs

Safari pre-programs the leftmost dial to use keyboard shortcuts so I can just spin the dial if I really want. The most important tabs are going to be command one, command two, command three, et cetera, through to command nine because that is an option in Safari. You know, if you look under the tabs, then you can do that. Every so often, I've ended up with my window kind of back to front and I've got a bunch of stuff like on the left side that I want to get rid of. So what you can do then is you can actually press option and then you can close the tabs to the left.
