The items below INITEX are read from the format list specified in
the most recently selected configuration file.
The Default config file sets the format list to LATEX and Plain.
The current format is indicated by a tick and will be the one used when you
typeset a file (although this will be overridden if ``Use Format in Log''
is ticked and a log file exists).
To change the current format, simply select a different format item.
automatically ticks the first format found when loading a
configuration file, so it's a good idea to place your preferred format first.
Note that if a non-default configuration file uses the ``?
''
character to avoid changing the format list then won't change the
current format.
