Jump To the Rightmost Tab In Safari

You can use Command plus the number keys to jump to the first, second, third, all the way up to the ninth tab in the current Safari window. But a new feature in macOS 10.13.4 is the ability to use Command+9 to jump to the rightmost tab. So if you have three tabs open, you can use Command+1 to Command+3 to jump to each, but Command+9 can also be used to jump to the last tab too.
