DORY

DO Repeat Yourself

But why?

There is one very powerful phrase that describes the 'why?' very well: "Wax-on, wax-off!"

Tired of hitting ctrl+w 20 times in a row?

Me too - so I just did it. I tried if my browser would behave as expected. And it did!

I went to the first tab I wanted to close by clicking on it with the mouse. Then, with the shift-button down, I clicked on the last tab. Now I held one hand before my eyes (peeking between 2 fingers) and hit ctrl+w.

It closed all those tabs. As one would expect.

Wow
