Lib/idlelib/config.txt

# IDLE reads several config files to determine user preferences.  This 
# file is the default config file.  When IDLE starts, it will look in
# the following four files in order:
#     config.txt                      the default config file
#     config-[win/unix/mac].txt       the generic platform config file
#     config-[sys.platform].txt       the specific platform config file
#     ~/.idle                         the user config file
# XXX what about Windows?
#
# The last definition of each option is used.  For example, you can
# override the default window size (80x24) by defining width and
# height options in the EditorWindow section of your ~/.idle file
#
# IDLE extensions can be enabled and disabled by adding them to one of
# the config files.  To enable an extension, create a section with the
# same name as the extension, e.g. the [ParenMatch] section below.  To
# disable an extension, either remove the section or add the 'enable'
# option with the value 0.
