How do you make the screen smaller?

I have accidentally swiped the screen somehow and managed to go to a one handed mode. I also can't replicate it. What is the exact gesture for this feature?

Swipe the on-screen buttons right or left at the bottom to go into one handed mode.

Touch the top or open side of the screen to return to normal.
