 1. Start Scratch.
  2. Go to the Costumes tab.
  3. Press the "Camera" button to open the camera window.
  4. Press "ESC".

 The camera window will close but leave the camera running on an XO (camera
 active LED on).  A user reopening the camera dialog will see a black
 picture, but has to press "Done" in said dialog to shutdown the camera
 properly so it can be used again.

 Seen in OLPC os 11.3.1 os884 on XO-1.75/Scratch 1.4 (XO {v16 in dialog;
 v20 in activity.info file}).
