Best way to switch between open files?

Evening all.

So, first few sessions with SW and all is good. Slowly working my way through the inbuilt tutorials to familiarise myself.

Really like the software!

I have a question; what is the easiest way to switch between files I may have open?

eg, I have a part file and a drawing file open at the same time. How do I quickly switch between the two?

(Inventor had 'tabs' at the bottom of the screen you could click).

TIA,
