Subject: How does `undo` know that `keyboard-quit`has been called?
Date: Fri, 07 Nov 2014 22:36:51 +0100 [thread overview]
Message-ID: <cc4sbmF8oioU1@mid.individual.net> (raw)
I would like to write a command that behaves like `undo`, that is: a
command that reverses its behaviour when the user calls `keyboard-quit`.
I have read the Lisp code for both `undo` and `keyboard-quit` and I
can't understand how `undo` achieves such behaviour. (I know that I
could always advise `keyboard-quit`.)
Thank you.
