05 Apr Apple Safari Shortcut to Get from Tab to Tab
To get to the rightmost open tab in Safari for Mac, press Command (⌘)-9 on the keyboard.
Again, this particular shortcut requires that macOS High Sierra 10.13.4 or later be installed on your Mac. If you have an older macOS edition, pressing the same shortcut will select your ninth tab from the left. In case you didn’t know, you can jump quickly to any of your first eight tabs by pressing Command (⌘)-1 to Command (⌘)-8.
macOS High Sierra 10.13.4 and up allows jumping to the rightmost open tab using Command-9
You can cycle through your open tabs even faster with a trackpad gesture: when there are more tabs than fit in Safari’s tab area, use your trackpad to swipe left or right over the tab bar to scroll through your open tabs like a pro.
