I'm studing lisp and I found this: (zoom in)^C ^C , but the text don't explain it, and I searched "^C ^C" in other places but didn't found anything. Can someone here help-me?
(I'm studying english yet, sorry if I wrote anything wrong)
"^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))
