Previously, taking screenshots required a keyboard shortcut (Ctrl + F12 iirc), which was inconvenient because you had to remove the headset. Now, to take screenshots, you can just press the System button and the trigger simultaneously on the Vive controller. No need to remove the headset.
You'll get two screenshots - a 3D version (side-by-side) and a 2D version.

The screenshots also show the chaperone bounds (visible in the sample shots above as the blue outline).
The screenshots can be uploaded to the Steam cloud and/or shared to Facebook.
