@appendix Standard Errors
Here is the complete list of the error symbols in standard Emacs,
grouped by concept. The list includes each symbol's message (on the
@code{error-message} property of the symbol), and a cross reference to a
description of how the error can occur.
Each error symbol has an @code{error-conditions} property which is a
list of symbols. Normally, this list includes the error symbol itself,
and the symbol @code{error}. Occasionally it includes additional
symbols, which are intermediate classifications, narrower than @code{error}
but broader than a single error symbol. For example, all the errors
in accessing files have the condition @code{file-error}.
As a special exception, the error symbol @code{quit} does not have the
condition @code{error}, because quitting is not considered an error.
