+ − 9 Here is the complete list of the error symbols in standard Emacs,
+ − 10 grouped by concept. The list includes each symbol's message (on the
+ − 11 @code{error-message} property of the symbol) and a cross reference to a
+ − 12 description of how the error can occur.
+ − 13
+ − 14 Each error symbol has an @code{error-conditions} property that is a
+ − 15 list of symbols. Normally this list includes the error symbol itself
+ − 16 and the symbol @code{error}. Occasionally it includes additional
+ − 17 symbols, which are intermediate classifications, narrower than
+ − 18 @code{error} but broader than a single error symbol. For example, all
+ − 19 the errors in accessing files have the condition @code{file-error}.
+ − 20
+ − 21 As a special exception, the error symbol @code{quit} does not have the
+ − 22 condition @code{error}, because quitting is not considered an error.
