cokebottle /kohk'bot-l/ n.
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.
