# 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'
