Does this have anything to do with the C programming language? – Praetorian Jul 15 '11 at 20:15

"^C^C" is not AutoLisp; that would be for/is the macro language for menus and such.
Caret-C does "mean" CTRL-C.
What it does in the macro language:
^c means: cancel
^c^c means: cancel twice.
In AutoCAD we hit the ESC key (twice to cancel a command). The ^C^C is "good practice". -i.e. Before we issue or start a new command we cancel any current command.
The equivalent in AutoLisp would be:
(command) (command)
or
(repeat 2 (command))

I think they refer to the control-character ctrl-c you enter after entering (zoom in) in the REPL.

As others have said, most likely it means Ctrl+C, especially if you're using emacs, where two Ctrl+C presses (usually written "C-c C-c" in the emacs convention, though) means "run this using the default interpreter" in some language modes.

If I'm not mistaken, ^C usually represents the "Ctrl+C" modified keypress.
It won't work in a console on Windows, as Ctrl+C also means "break (execution)", but if you press Ctrl+V, Ctrl+P, etc., you'll see what I mean.
