# There are two parameters controlling the action of this module:
#
# browser.interface - if this is 'textual', it overrides the second parameter
# and goes to screen reader PDA mode
#
# environment.remote - if this is 'on', the routines controll the remote
# control, otherwise they render the main window controls; ignored it
# browser.interface is 'textual'

=item show_course()
Little texts
=item initlittle()
=item menubuttons()
This gets called at the top of the body section
=item show_return_link()
=item registerurl()
This gets called in the header section
=item innerregister()
This gets called in order to register a URL, both with the Remote
and in the body of the document
=item loadevents()
=item unloadevents()
=item startupremote()
=item setflags()
=item maincall()
=item load_remote_msg()
=item get_menu_name()
=item reopenmenu()
=item open()
