There are a few ways to create shortcuts between tabs on a Mac. One way is to use the "Command + Option + [arrow key]" shortcut. For example, if you wanted to create a shortcut between the first and second tabs, you would hold down the "Command" key, the "Option" key, and then press the left arrow key. Another way to create shortcuts between tabs is to use the "Command + [number]" shortcut. For example, if you wanted to create a shortcut between the first and second tabs, you would hold down the "Command" key and then press the "1" key.
