cokebottle
Free On-line Dictionary of Computing
<character, humour> /kohk'bot-l/ Any unusual character, particularly one you can't type because it isn't on your keyboard. MIT people used to complain about the "control-meta-cokebottle" commands at SAIL, and SAIL people complained about the "altmode-altmode-cokebottle" commands at MIT. After the demise of the space-cadet keyboard, "cokebottle" was used less, but was often used to describe weird or non-intuitive keystrokes.
The OSF/Motif window manager, "mwm" keystroke for switching to the default keybindings and behaviour is control-meta-bang. Since exclamation mark might be thought to look like a Coke bottle, Motif hackers referred to this keystroke as "cokebottle".

The Jargon File
Any very unusual character, particularly one you can't type because it isn't on your keyboard. MIT people used to complain about the ‘control-meta-cokebottle’ commands at SAIL, and SAIL people complained right back about the ‘escape-escape-cokebottle’ commands at MIT. After the demise of the space-cadet keyboard, cokebottle faded away as serious usage, but was often invoked humorously to describe an (unspecified) weird or non-intuitive keystroke command. It may be due for a second inning, however. The OSF/Motif window manager, mwm(1), has a reserved keystroke for switching to the default set of keybindings and behavior. This keystroke is (believe it or not) ‘control-meta-bang’ (see bang). Since the exclamation point looks a lot like an upside down Coke bottle, Motif hackers have begun referring to this keystroke as cokebottle. See also quadruple bucky.
