How do I get Chrome-like tab switching shortcuts in Safari?

I much prefer the way Chrome allows me to use ⌘+# key to switch directly to an open tab. For example: ⌘+3 takes me directly to tab 3 in Chrome, but in Safari it loads the third bookmark from the bookmark bar in the current tab.

How can I make Safari behave like Chrome when I'm using ⌘+# key shortcuts and switch tabs instead of loading bookmarks?
