Sometimes you need to go back to the previous page. Why use your mouse for that when you can let your fingers do the work with a little Keyboard Kung Fu.
Substitute the back button with this simple move
Holding your thumb on the ⌘ key, tap the [ key with your index or middle finger.
You can also go forward to the page you just left by using the Command key with the right bracket, ⌘].
Not just for web browsers
The command-bracket key combination not only works in Safari, Chrome, Firefox or any modern web browser but it’s also very useful for navigating while in Finder.
Try it now – leave this page and go back to the previous page using ⌘[ and then go forward with ⌘] to return to this page.
