 4.3 Catching the errors
 =======================
 
 Once you've formatted your document you may 'debug' it, i.e.  browse
 through the errors (La)TeX reported.  You may also have a look at a
 nicely formatted list of all errors and warnings reported by the
 compiler.
 
  -- Command: TeX-next-error ARG REPARSE
      ('C-c `') Go to the next error reported by TeX.  The view will be
      split in two, with the cursor placed as close as possible to the
      error in the top view.  In the bottom view, the error message will
      be displayed along with some explanatory text.
 
      An optional numeric ARG, positive or negative, specifies how many
      error messages to move.  A negative ARG means to move back to
      previous error messages, see also 'TeX-previous-error'.
 
      The optional REPARSE argument makes AUCTeX reparse the error
      message buffer and start the debugging from the first error.  This
      can also be achieved by calling the function with a prefix argument
      ('C-u').
 
  -- Command: TeX-previous-error ARG
      ('M-g p') Go to the previous error reported by TeX.  An optional
      numeric ARG specifies how many error messages to move backward.
      This is like calling 'TeX-next-error' with a negative argument.
 
    The command 'TeX-previous-error' works only if AUCTeX can parse the
 whole TeX log buffer.  This is controlled by the 'TeX-parse-all-errors'
 variable.
 
  -- User Option: TeX-parse-all-errors
      If t, AUCTeX automatically parses the whole output log buffer right
      after running a TeX command, in order to collect all warnings and
      errors.  This makes it possible to navigate back and forth between
      the error messages using 'TeX-next-error' and 'TeX-previous-error'.
      This is the default.  If nil, AUCTeX does not parse the whole
      output log buffer and 'TeX-previous-error' cannot be used.
 
    As default, AUCTeX will display a special help buffer containing the
 error reported by TeX along with the documentation.  There is however an
 'expert' option, which allows you to display the real TeX output.
 
  -- User Option: TeX-display-help
      If t AUCTeX will automatically display a help text whenever an
      error is encountered using 'TeX-next-error' ('C-c `').  If nil a
      terse information about the error is displayed in the echo area.
      If 'expert' AUCTeX will display the output buffer with the raw TeX
      output.
