Rolling Calculations In Spotlight

Everyone knows you can use Spotlight for calculations. Press Command+Space and then type something like 3+4+5 and you’ll see 12 as the result. You can then use Command+c t copy that result. You don’t need to select anything. If you then use Command+a (select all) and Command+v (paste) you can place that result back into Spotlight to start a new calculation with that number.
