   Quitting with @kbd{C-g} is the way to get rid of a partially typed
-command, or a numeric argument that you don't want.  It also stops a
-running command in the middle in a relatively safe way, so you can use
-it if you accidentally give a command which takes a long time.  In
-particular, it is safe to quit out of a kill command; either your text
-will @emph{all} still be in the buffer, or it will @emph{all} be in
-the kill ring, or maybe both.  Quitting an incremental search does
-special things, documented under searching; it may take two successive
-@kbd{C-g} characters to get out of a search (@pxref{Incremental
-Search}).
