When cinematic mode (also known as F8 mode) hasn't got a key assignt to it, and you press the mute button on your keyboard (or via mouse, you can assign media buttons on your thumbuttons in the drivers) then cinematic mode will be activated in creative and survival in any world.

Unplugging the power cord to my laptop does the same thing as pressing the f7 key.

Easy fix for users: Bind the camera to f8.
Easy fix for Mojang: Bind the camera to f8.
Its not that hard; you can ignore the underlying problem (unrecognized keys == none), and just fix all instances.
Confirmed.
